... ELECTROLYSIS OF COPPER Aim: To investigate the effect of the copper anode after electrolysing it in Copper Sulphate solution for certain periods of time. Planning: Introduction: Electrolysis is the process of splitting up compounds or substances by passing an electric current through it. The substance being electrolysed is called an electrolyte. An electrolyte is a substance that cannot conduct when solid but can when molten or dissolved. In electrolysis, various equipment are involved in order to make the experiment successful. First of all, a power pack is needed. This acts as a pump to push electrons through the circuit i.e.) it provides energy. There are two electrodes involved. An electrode allows electrons to enter or leave a solution. It completes an electrical circuit. One electrode is called the Cathode, and one the Anode. The cathode is the negative electrode thus attracting the positive ions called cations. Electrons are drawn TOWARDS it. The anode on
