Rusty nail experiment

Follow FizzicsEd 150 Science Experiments:

You Will Need:

• 6 Test tubes or plastic cups
• 6 Steel nails (avoid galvanised ones)
• Lemon juice
• Cooking oil.
• Optional: Saltwater, detergent.
• Adult supervision

• Instruction

Set up the 6 test tubes or cups as shown in the picture above. This experiment is very much about  variable testing !

Take a photo and write down your observations of each nail at the start of the experiment. This is also a good time to enter this into your own  classroom blog !

Optional: Weigh each nail with an accurate scale at the start and the end of the experiment.

Optional: Try different nails in the same liquid… do they rust differently?

Over the coming days take recordings of each nail’s condition.

– Which nail showed rust first? – If you were able to weigh each nail at the end of the experiment, was there any difference between the nails? Why?

This setup is just one way of running this classic rust experiment. You could also try the following experiment conditions too:

• nail completely submerged in water vs. half submerged.
• nail completely submerged in water with a layer of oil over the top of it.
• nail in salt water vs. nail in pure salt

You could also try normal steel nails vs. steel wool to investigate the effect of surface area on rusting rates as well.

Why Does This Happen?

Rusting is the oxidation of metal, whereby the oxygen in the environment combines with the metal to form a new compound called a metal oxide. In the case of iron rusting, the new compound is called iron oxide… also known as rust!

This science experiment is all about controlling variables to explore which material will rust an iron nail first.

Variables to test

More on variables here

• Try boiling the water… does this make the nail rust faster, slower or is there no impact on the rusting time?
• What happens when you use different liquids?
• If you scratch the nail first, will it rust faster or slower?
• What if you use iron wool and iron filings instead?
• Try galvanised nails

Further information

Rusting, also known as corrosion, is the reddish-brown layer formed over an iron when exposed to air and water. Rusting occurs mainly because of a chemical reaction between iron with water and oxygen in the air.

Simple formula…     

Water + Oxygen + Iron = Rusting

The chemical reaction usually occurs very slowly and it is an oxidation process. Rusting can also occur on other metals such as copper and they may not always be called ‘rust’.

Rusting can also occur in water. The carbon dioxide gas in the air mixes with water to form a weak acid called carbonic acid. This acidified water can dissolve some of the iron and water begins to break down into oxygen and hydrogen. The free oxygen reacts with the dissolved iron to form iron oxide or rust.

How many day will nail rust in tap water,vinegar,salt water, sprit and cooking oil

Hi Kolwawole! Thanks for your question. The time to rust for the nail is highly dependent on the liquid the nail is immersed in. In water, you tend to see the beginnings of rust within a couple of days or so whereas other liquids take longer. Try the experiment out and let us know your results!

I bought non galvanised steel nails (they are called bright steel) and I have had them in my liquids (salt water and tap water) for a week now and instead of showing signs of rust they have just gone a grey colour. Do you know why? How can I adjust the experiment to make them actually rust? Thanks

Interesting! It looks like that if your nails were non-galvanised, it would have been to do with dissolved minerals such as carbonates in your water. The more carbonates, the ‘harder the water’. The harder the water the more difficult it is to rust a hot-dip galvanised nail as it affects the pH and the action of sodium and chlorine ions that come from the dissolved salt in the water ( see this link ). The thick layer of Chromium and Zinc on the galvanised steel slows the rusting as it prevents oxygen reaching the metal (at least for a while). You can actually see this affect by scratching off part of the galvanised layer and then letting this area rust as you’ve removed the protection ( read up on crevice corrosion ).

The thing is, your bright steel nails are non-galvanised. This means they should have little to no protection to the salt. If left for longer, the nails should begin to corrode on the outside. The rust formed on the outside is still permeable by the water and salt ions, which means that we would expect this rusting to happen underneath the top layer of rust as well. This should continue until the nail becomes completely iron oxide (rust). Let us know if this happens! For full details on the chemistry of nails rusting, check out csun.edu.

Thanks for your question!

I’m really confused about how can I weigh corrosion in metals. Can you please help.

Hi Rouzana! If you are able to have access to laboratory scales within a high school, you should be able to take a measurement of each nail mass before and after the experiment. The more sensitive the scales, the better!

hi can you please tell me the aim and the hypothesis of this experiment. thanks

Hi! Here’s something that could start you off; – Aim; To determine which liquid produces the most rust on an iron nail. – Null Hypothesis; There will be no change in rust on an iron nail when immersed in ‘ABC liquid’. Have fun!

Hi! Do you know what type of reaction this and also the science behind it? Thank you!

Hi Lara! This is an example of a Redox reaction, wherein this case the iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. See further details here!

I wanted to do a variation of this experiment for my high school class. Instead of weighing the change in mass to determine the amount of oxidation, I was wondering if there was a chemical that could dissolve only the nail(iron or any other metal) leaving the remaining iron oxide behind.

Sorry Michelle, I’m not sure of a chemical that will do this. If you find out please let us know!

hey can you tell us the chemical formula of the equation iron+water+oxygen= hydrated iron(III) oxide Should we cover the bottle of water to hasten the rusting process ? thank you

Hi Viv! There’s actually a few things going on here over three separate reactions: A great summary of the three reactions can be found here The final balanced equation is below, however this covers both Fe(II) and Fe (III) ions. 4Fe + 3O 2 + 6H 2 O → 4Fe(OH) 3

If I have four solutions (water, salty, bleach and with oil) which will corrode the fastest? the slowest?

Hi!, I placed screws/nails in vinegar and lemon juice and after 9 days they turned black, I was wondering what is the cause of this?

Hi! The acid from both liquids removed the outer coating and exposed the underlying metal to the air which caused oxidation

hi, I have a doubt, I used the ss steel screw ( nail) and I kept them in vinegar, cooking oil & lemon juice. But when I checked it in the next day the screw in the vinegar turned silver to black. The same happened the same but it happened to the lemon juice

Hi! Both the vinegar & lemon juice are acids that removed the coating and allowed the underneath to oxidise.

What is their rate of corrosion (Reaction)? thank you

Hi! This is dependent on the concentration of the acids and the temperature

what are the factors that affect/speeds-up corrosion?

Solution concentration & type as well as temperature. Isolate a variable and see which make the greatest effect!

what liquid makes nails/screws rust the fastest?

Hi Piper! Please try the experiment to find out and let us know!

Do you know what are the independent, dependant and controlled variables in the experiment.

Hi! Please have a read of this article to help you with this answer 🙂 https://www.fizzicseducation.com.au/articles/variables-teaching-the-heart-of-science-experiments/?recaptcha_response=

Experiments on the Rusting of Iron Nails

Science Fair Project on Soda Dissolving a Nail in Four Days

Rust is a broad topic of discussion for science classrooms at all grade levels. While elementary teachers present rusted metal as a simple example of a chemical reaction, high school instructors point to rust in explanations of oxidation and reduction reactions. Students in public school or home school are able to perform experiments on rusting iron nails for class research assignments or science fair projects.

Comparing Corrosion

Intermediate students who prepare for assignments in advance can determine which liquids cause rust formation fastest on submerged iron nails. Gather six beakers or drinking glasses. Add 1 cup of tap water to the first, 1 cup of salt water to the second, 1 cup of a carbonated lemon-lime soda to the third, 1 cup of pickle juice to the fourth container, 1 cup of orange juice to the fifth and 1 cup of white vinegar to the last cup. Hypothesize what liquid will cause a nail to rust first. Submerge one iron nail in each container and set the beakers or glasses in a place they will not be disturbed. Observe the nails daily to check for rust formation. The nails in water should both form rust within three weeks, and the vinegar should rust a nail approximately one week later. The soda and juices should not cause any rust to form on the nail.

Accelerated Oxidation

A dessicator is a two-level cabinet that maintains contents in a completely dry atmosphere. Samples are placed on a layer of wire gauze, and a drying agent, such as silica gel, is stored on the base level. Purchase a small dessicator online or from a medical supply store. Place three clean, dry iron nails on the wire gauze layer in the dessicator and put 10 grams of calcium chloride crystals on the bottom of the dessicator. Dip three nails in water before hanging them outside the dessicator by using wire to attach them to the dessicator door handle. Observe and record data for one week. While the nails outside the dessicator should form rust, the nails inside will remain clean. Students should see from the results that moisture is a key element in rust formation and must present in the air surrounding iron for oxidation to occur.

Temperature Changes

Hypothesize whether cold or warm air temperatures will affect the rate at which rust forms on iron nails.Gather nine iron nails and three beakers or glass containers of the same size. Place three nails into a container filled with tap water. Place three nails in a container and fill with ice cubes. Place the remaining nails in a container filled with tap water and place under a heat lamp. Leave all three containers uncovered in an undisturbed area and observe daily for one week. Ice must be added to the second container frequently to maintain a cold environment throughout the experiment. Oxygen, the primary component of rust formation, combines with other elements, including iron, more readily at warmer temperatures, so the nail under the heat lamp should rust first, while the nail in ice should be the last to form rust on its surface.

Density of Rust

Density experiments are versatile to fit most age levels. Students should hypothesize how the oxidation reaction that produces rust on iron nails affects the density of the nails. Purchase 2 pounds of iron nails and separate into 1 pound groups. Ensure the mass and volume of each group is equivalent. Leave one group indoors so rust will not form on them. Allow the second group to rust naturally outside, or accelerate the rust formation using a technique from the previous experiments. When oxidation is complete, calculate the mass and volume of the second group to determine whether any change in density occurs during oxidation. Rust is less dense than iron, but a gram of iron will yield more than 1 gram of rust, so students should observe a weight gain, and therefore an increase in density, in the rusted set of nails.

Preventing rust

In association with Nuffield Foundation

• Five out of five
• No comments

Try this class practical or demonstration to test and assess a variety of methods for preventing rust

In this experiment, students protect iron nails using painting, greasing and sacrificial protection. The nails are placed in test tubes and covered with corrosion indicator solution. This contains gelatine and so sets to a jelly-like consistency. The indicator changes colour from yellow to blue to show where rusting is taking place. By comparing the amount and position of the blue indicator on each nail, students can assess the effectiveness of the different types of protection.

This can be set up as either a demonstration or a class practical. Students can be told how to carry it out or left to plan it for themselves. If they are to plan it themselves then it would be a good idea to demonstrate the use of the indicator with unprotected iron nails, before they start to think about their plans.

Even as a demonstration, the majority of the work can be done by individual pupils. They can paint the nails, cover them in plastic, wrap them in another metal and so on. It is not necessary to do all the suggested tests – around six, including the control nail, will give the idea. It is probably best to include some familiar methods of preventing rust, such as painting, as well as at least one example of sacrificial protection, such as wrapping with magnesium.

Although the results are obtained quickly for a corrosion practical, it will still take around half an hour for the indicator to change and so it is advisable to have something else planned for the students to do while they wait for the colour to develop.

• Eye protection
• Test tubes, at least 6 (see note 1)
• Test tube rack
• Clingfilm or similar plastic film
• Marker pen or labels for test tubes
• Iron nails, at least 6 (see note 2)
• Galvanised (zinc coated) nails, x2 (see note 3)
• Stainless steel nail, screw or bolt
• Copper foil, small piece
• Magnesium ribbon, about 2 cm
• Zinc foil, small piece
• Cleaning solution, dilute sodium carbonate (see note 4)
• Dilute hydrochloric acid, 1 M, about 10 cm 3
• Paint plus a small brush (see note 5)
• Oil (see note 6)
• Gelatine, 5 g
• Potassium hexacyanoferrate(III), 0.2 g

Equipment notes

• Cheap soda glass test tubes can be used so that stained ones can be discarded after use.
• The nails for this experiment will ideally be identical and should be iron rather than stainless steel. They can be obtained from a hardware store. They should be cleaned of rust prior to the experiment. This can be achieved with dilute (about 1 M) hydrochloric acid, followed by thorough rinsing in cold water.
• Clout nails from a hardware store are a good source of galvanised nails. They can be reused.
• A suitable cleaning solution is a dilute (around 5%) solution of sodium carbonate with a few drops of ordinary detergent added.
• The paint must not be water soluble and should ideally dry quickly. Acrylic paint or correcting fluid (egTippex) is ideal.
• Any oil which is safe for pupils is suitable. Cooking oil is probably the easiest to use.

Health, safety and technical notes

• Read our standard health and safety guidance.
• Wear eye protection throughout.
• Iron, Fe(s), copper, Cu(s), magnesium, Mg(s), zinc, Zn(s) – see CLEAPSS Hazcards HC055A , HC026 , HC059A and HC107 .
• Sodium carbonate solution, Na 2 CO 3 (aq) – see CLEAPSS Hazcard  HC095A  and CLEAPSS Recipe Book RB080.
• Dilute hydrochloric acid, HCl(aq) – see CLEAPSS Hazcard  HC047a  and CLEAPSS Recipe Book RB043.
• Potassium hexacyanoferrate(III), K 3 Fe(CN) 6 (s) – see CLEAPSS Hazcard HC079 .
• Prepare the corrosion indicator shortly before the lesson as it does not keep well. Make a warm solution of 5 g gelatine in 100 cm 3 water and then dissolve 0.2 g potassium hexacyanoferrate(III) in it. Keep the solution warm but not hot, otherwise toxic gases can be evolved. If you have access to one, a magnetic stirrer with hotplate is ideal for this but it is not essential. No hazard label is required for the solution.
• Select some nails which do not show any signs of rusting. Clean them thoroughly with the cleaning solution and dry them.
• Place one nail as a control into a test tube.
• Treat the other nails as suggested below. Not every test needs to be done. Label each test tube.
• Wrap one nail in thin plastic film, such as ‘clingfilm’.
• Paint one nail and let it dry.
• Coat one nail with Vaseline or other grease, or oil.
• Wrap a small piece of magnesium ribbon or zinc foil around a section of a nail.
• Wrap a small piece of copper foil around a section of a nail.
• Place these nails in separate test tubes.
• Place a stainless steel nail, bolt or screw into a test tube.
• Place two galvanised (zinc coated) nails, one which has been scratched with a file to remove a patch of zinc coating, into a test tube.
• Carefully pour the corrosion indicator into each test tube, completely covering each nail. Leave for at least half an hour.

Teaching notes

After about half an hour it will be possible to see the indicator changing from the starting yellow colour to dark blue in patches on the nails. These dark blue patches indicate areas where rusting is starting.

Rusting is a complex reaction between iron, oxygen and water to form hydrated iron(III) oxides. Initially iron goes into solution as Fe 2+ ions, losing electrons:

Fe(s) → Fe 2+ (aq) + 2e –

This is oxidation and occurs on the iron where the protective oxide layer is weakest or damaged. Such areas are called anodic. The Fe 2+ ions combine with the indicator to form a blue solid.

In the absence of the indicator the Fe 2+ ions combine with OH - ions produced at cathodic areas by reduction of oxygen:

O 2 (aq) + 2H 2 O(l) + 4e –  → 4OH – (aq)

(By adding a few drops of phenolphthalein indicator solution when making up the gelatine mixture, so-called ‘Ferroxyl indicator’ is obtained. This indicator will show the cathodic areas as well, as the hydroxide ions cause the phenolphthalein to turn pink.)

The iron(II) hydroxide formed is oxidised further by oxygen, to form rust, Fe 2 O 3 .xH 2 O. For more detail on the reactions involved in the rusting process, take a look at this page on the chemistry of rust from Corrosion Doctors.

Typically, the magnesium wrapped nail will rust the least. The magnesium donates electrons to the iron, which slows down the rusting process. This is effective even for the parts of the iron which are not in direct contact with the magnesium. The magnesium corrodes instead of the iron, ‘sacrificing’ itself. This is called sacrificial protection, and is used commercially to protect iron structures in corrosive environments.

The nail wrapped in copper will rust the most. This is due to the opposite process. The more reactive metal, iron, donates electrons to the copper and becomes electron deficient itself. This increases the rate of the rusting.

The other nails will rust in a variable way, depending on how effectively they have been coated. Any chips in the paint, or gaps in the plastic or grease, will leave some of the iron nail exposed to oxygen and water, and these will be the first areas on those nails to rust. It is worth making the comparison with nails in contact with magnesium, which are protected even in areas that are not directly touching the magnesium. Alloying is also an effective method of rust prevention and chips and scratches in the surface are generally not important. As a result, the stainless steel nail will generally not rust much, if at all.

Students could be asked to tabulate the results of the experiment. They could also think about where each method of rust prevention is used in real life, why that method is chosen and how effective it is.

The Unique Burial of a Child of Early Scythian Time at the Cemetery of Saryg-Bulun (Tuva)

<< Previous page

Pages:  379-406

In 1988, the Tuvan Archaeological Expedition (led by M. E. Kilunovskaya and V. A. Semenov) discovered a unique burial of the early Iron Age at Saryg-Bulun in Central Tuva. There are two burial mounds of the Aldy-Bel culture dated by 7th century BC. Within the barrows, which adjoined one another, forming a figure-of-eight, there were discovered 7 burials, from which a representative collection of artifacts was recovered. Burial 5 was the most unique, it was found in a coffin made of a larch trunk, with a tightly closed lid. Due to the preservative properties of larch and lack of air access, the coffin contained a well-preserved mummy of a child with an accompanying set of grave goods. The interred individual retained the skin on his face and had a leather headdress painted with red pigment and a coat, sewn from jerboa fur. The coat was belted with a leather belt with bronze ornaments and buckles. Besides that, a leather quiver with arrows with the shafts decorated with painted ornaments, fully preserved battle pick and a bow were buried in the coffin. Unexpectedly, the full-genomic analysis, showed that the individual was female. This fact opens a new aspect in the study of the social history of the Scythian society and perhaps brings us back to the myth of the Amazons, discussed by Herodotus. Of course, this discovery is unique in its preservation for the Scythian culture of Tuva and requires careful study and conservation.
