Question

During the electrolysis of aqueous CuSO4 using Cu electrode. Which of the following species is formed at anode?

Answer 1

Answer:

Cu2+ and 2e

Explanation:

During the electrolysis of CuSO4 using copper electrodes the anode reduces in mass .

At the anode sulphate ions are preferentially discharged but the copper electrode is the one that reacts because of its high level in the reactivity series

Copper therefore reacts to form copper ion and two electrons.

Cu2+ and 2e.

Answer 2

Explanation:

Cu2+ and 2e
