In electrolysis of aqueous copper sulphate, the gas at anode and cathode is .

A

`O_(2)` and `H_(2)`

B

`SO_(2)` and `H_(2)`

C

`H_(2)` and `O_(2)`

D

`SO_(3)` and `O_(2)` metal

Text Solution

Verified by Experts

The correct Answer is:
A
Cathode : `2H_2O(l)+2e^(-)toH_2(g)+2OH^(-)(aq)`
Anode : `H_2O(l)to2H^(+)(aq)+1/2O_2(g)+2e^(-)`
