Pencil Electrolysis Introduction: The process by which we separate the elements hydrogen and oxygen from water is called electrolysis. The word "lysis" means to dissolve or break apart, so the word "electrolysis" literally means to break something apart (in this case water) using el ectricity. It is difficult to
PDF Electrolysis: Splitting Water
Part 1 - Electrolysis of water In this section, you will use electricity to split apart water molecules! 1. Set up the electrolysis apparatus as shown in the picture. a) Pierce two round holes in the bottom of a plastic cup. (Figure 1a) b) Sharpen two wooden pencils on both ends (after pulling off the eraser). Insert the pencils into the
PDF The bubbles at both pencil tips look the same: Are they the same or
A color-changing indicator can tell you whether a substance is an acid and or a base. Water or H2O molecules can change to form the ions H3O+ (acid) and OH-(base). Bubbles and color changes are signs that a chemical change may have occurred. Electrolysis is the process of using electricity to facilitate chemical reactions.
PDF Electrochemistry: Electrolysis of Water Lab
The purpose of this experiment is to investigate the electrolysis of water in an electrochemical cell. Two carbon pencil "leads" (graphite rods) will be inserted into the opposite ends of a Petri dish containing water, sodium sulfate, and bromthymol blue. An electric current will be passed through the solution by
PDF Electrolysis of Water
By adding electricity to water and providing a path for the different particles to follow, the water can be separated into hydrogen and oxygen. In this experiment you will be taking a sample of salt water and add a flow of electricity to it (the electrolysis). You will see the hydrogen and oxygen. 2. bubbling up.
Electrolysis of Water Experiment
1. Fill the beaker or glass with warm water. 2. Carefully remove the erasers and metal sleeves so you can sharpen both ends of each pencil. These pencils are your electrodes. The graphite in them will conduct electricity, but won't dissolve into the water. 3.
PDF Electrolysis: Breaking Water with Electricity
1) Half-cup water + 1 full spoon Epsom salt 2) Half-cup water + 1 full spoon table salt (NaCl) • Push 2 sharpened pencils through a piece of cardboard. Rest the cardboard on top of each cup, so that pencil tips are in the water. • Connect the tips of the pencils to the two terminals of a 9V battery. Record what you see at the pencil tips.

Ensure no pencil ends are touching 8. Hold the 9v battery over the two pencils, as per the diagram above, touching each point of the pencil to a contact point for up to ten seconds 9. Bubbles of hydrogen (H 2) and oxygen (O 2) will now form at each pencil tip, as the water molecules in your glass have now been separated Electrolysis is one way we

Always have an adult with you to help you during your experiment. Always wear eye protection and gloves when doing chemistry experiments Procedure: 1. In our electrical setup, we will be using pencil leads as our electrodes (electrical contacts). Regular cooper wire would corrode too fast to run our electrolysis machine very long. The
Electrolysis of Water Experiment
Electrolysis of Water Experiment. Energy is stored in the bonds of molecules. When these bonds split apart, the energy released can be used to do work. Breaking apart liquid water molecules into hydrogen and oxygen gas creates an enormous amount of energy, which can be turned into useful electricity to power our homes and cars.
