What will happen during the electrolysis of aqu eous solution of `CuSO_(4)` in the presence of Cu electrodes?

Options

A. Copper will deposite at cathode.
B. Copper will dissolve at anode.
C. Oxygen will be released at anode.
D. Copper will deposite at anode.

Answer

A

Explanation

Electrolysis of `CuSO_(4)` can be represented by two half-cell reactions these occurring at cathode and anode, respectively, as given below:
At cathode: `Cu^(2+)+2e^(-) to Cu(s)`
At anode: `Cu(s) to Cu^(2+)+2e^(-)`
In above reaction Cu will deposite at cathode while copper will dissolve at anode. hence, (a) and (b) are the correct options.
