From a solution of `CuSO_4` the metal used to recover copper is

From a solution Cuso_4 the metal used to recover copper is

From a solution of copper sulphate, the metal used to recover copper, is 1)Na 2)Ag 3)Hg 4)Zn

If 1 faraday of electricity is passed through a solution of CuSO_4 the amount of copper deposited will be equal to its :

A solution of CuSO_4 is electrolysed between copper electrodes by a current of 10 Amperes passing for one hour. What changes occur at the electrodes and in the solution?

The mass of copper deposited from a solution of CuSO_4 by passage of 45 A current for 965 second is (Mol . Wt. pf Copper = 63.5 ).

2.5 Faraday of electricity are passed through a solution of a solution of CuSO_4 . The Number of gram equivalents of copper deposited on the cathode are :
