electrolysis of dilute copper sulphate coursework

Electrolysis always involves a flow of copler in the external wires and electrodes and a flow of ions in the electrolyte and there is always a reduction at the negative cathode electrode which attracts positive ions, cations and an oxidation at the positive anode electrode which attracts negative ions, anions and it is the ions which are discharged to give the products.

Electrolysis of copper chloride is a way of splitting up decomposition of the compound copper chloride using electrical energy.
