electrolysis of molten lead bromide experiment

Apparatus1. Eye protection (for students and demonstrating teacher) 2. Access to a fume cupboard 3. Porcelain crucibles, about 2.5 cm in …

Figure 3: Apparatus set up for the microscale electrolysis of molten lead bromide. The positive electrode is a carbon fibre rod and the negative electrode is an iron nail. A small spirit burner provides sufficient heat to melt …

One of the common compounds to electrolyse molten is lead (II) bromide - partly because the products are easily visible, and partly because its melting point isn't too high. An experimental set-up would look something like this: Nothing …

Electrolysis of Lead Bromide. Lead bromide must be heated until it is molten before it will conduct electricity. Electrolysis separates the molten ionic compound into its elements. The reactions at each electrode are called half equations. …

The electrolysis of molten lead bromide produces the brown bromine gas as a product. The bromide ions are attracted to the anode, where they donate electrons to form bromine gas. Since the bromide ions lose electrons, we also call this process an oxidation.

Pb2+ and Br- ions are present in the molten lead (II) bromide, PbBr2. At the anode, bromide ions, Br- are discharged by donating electrons to form bromine molecules, Br2. At the cathode, each lead (II) ion, Pb2+ is discharged by …
