Which one of the following reactions occurs at the anode on electrolysis of aq., solution of CuCl_(2) ?

Answer»

`Cu to Cu^(2+) + 2 e^(-)`
`2 Cl^(-) to Cl_(2) + 2E^(-)`
`2 H_(2)O to O_(2) + 4 H^(+) + 4 e^(-)`
`4 Cl^(-) + 2 H_(2)O to 4 HCL + O_(2) + 4 e^(-)`

SOLUTION :`Cl^(-)` ions are oxidizedmore easily than `H_(2)O`.
