2 In an electrolysis of copper sulphate between copper electrodes the total mass of copper deposited at the cathode was 0.153 g and the masses of copper per unit volume of the anode liquid before and after electrolysis were 0.79 and 0.91 g respectively. Calculate the transference number of the Cu2 and SO24- ions.

1 A solution of silver nitrate containing 12.14 g of silver in 50 ml of soluti on was
electrolysed between platinum electrodes. After electrolysis, 50 ml of the
anode solution was found to contain 11.55g of silver, while 1.25 g of metallic
silver was deposited on the cathode. Calculate the tran sference number of
Ag+ and NO,-jons.
