Electrolysis is the break down of a substance using electricity. Electrolysis only occurs when an ionic substance is molten or is a solution. A substance that can be electrolysed is called an electrolyte.

Copper is a very unreactive metal it's even below hydrogen in the reactivity series. This means it won't even react with water. Therefore, copper is very easily extracted from its ore by reduction, when it needs to be pure it is purified by electrolysis.

The experiment carried out was intended to observe the amount of Copper (Cu) metal deposited during the electrolysis of Copper Sulphate solution (CuSo4) using Copper electrodes, when variables were changed. The following factors may have affected the amount of Copper on the cathode.

It is possible to predict that there is a connection between the voltage and th
