Question

Predict the products of electrolysis of each of the following :

(i). An aqueous solution of CuSO4 using inert electrodes ( e.g. platinum electrodes) :

(ii). An aqueous solution of CuSO4 using attacking electrodes ( e.g. copper electrodes) ​

Answer 1

Answer:

Answer: The electrolysis of an aqueous solution of copper sulphate using copper electrodes (i.e. using active electrodes) results in transfer of copper metal from the anode to the cathode during electrolysis. The copper sulphate is ionised in aqueous solution.

Explanation:

When an aqueous solution of CuCl
