By the electrolysis of aqueous solution of `CuSO_(4)`, the products obtained at both the inert electrodess are:

Options

A. `O_(2)` at anode and `H_(2)` at cathode
B. `H_(2)` at anode and Cu at cathode
C. `O_(2)` at anode and Cu at cathode
D. `H_(2)S_(2)O_(8)` at anode and `O_(2)` at cathode.

Answer

C

Explanation

at anode `2H_(2)OtoO_(2)+4H^(+)+4r^(-)`
at cathode `Cu^(2+)+2e^(-)toCu`
