Copper can be deposited from acidified copper sulphate and alkaline cuprous cyanide. If the same current is passed for a definite time `:`

Options

A. The amount of copper deposited from acidic copper sulphate will be higher.
B. The amount of copper deposited from alkaline cuprous cyanide will be higher
C. The same amount of copper will be deposited.
D. None of these

Answer

b

Explanation

Alkaline solution will keep `H^(o+)` low so that there is a very small concentration. Hence, chances of `H^(o+)` getting reduced to `H_(2)` along with `Cu` are lesser in alkaline cuprous cyanide as compared to acidified copper sulphate.
