An experiment showing a useful application of electrolysis.
The electrolysis of salt (sodium chloride) solution performed in a U-shaped test tube with universal indicator.
Electrolysing molten lead(II) bromide
In this demonstration students will see that lead(II) bromide only conducts electricity when it is molten, and that the products of electrolysis are metallic lead and bromine.
Electrolysis of copper(II) sulfate solution
Students look at what happens when a constant electric current is passed through an aqueous copper(II) sulfate solution.
Electrolysis of zinc chloride
Demonstration showing that an ionic compound will not conduct electricity when solid, but will do so when molten.
Exploding bubbles of hydrogen and oxygen
Bubbles containing a mixture of hydrogen and oxygen gas, produced by electrolysis, are ignited and explode.
Identifying the products of electrolysis
This experiment allows students to investigate the products formed by electrolysing various solutions.
Preferential discharge of cations during electrolysis
This experiment shows the order in which cations are discharged during electrolysis.
Quantitative electrolysis of aqueous copper (II) sulfate
This demonstration experiment shows how to find the value of the Faraday constant using electrolysis.
Reaction of zinc with iodine
In this experiment students note the differences between a metal and a non-metal, and their reaction to form a metal salt.
