In the electrolysis of copper (II) chloride solution, the mass of cathode increased by 3.15 g At copper anode, we will have

Options

A. the liberation of 1120 mL of `Cl_(2)` at STP
B. the liberation of 560 mL of `O_(2)` at STP
C. the loss of 3.15g of Cu
D. the gain of 3.15 g of Cu

Answer

A

Explanation

Since anode is copper, the reaction occuring here is Cu at anode will `Cu rarr Cu^(2+)2e^(-)` . Thus loss of Cu C also be equal to 3.15 g
