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,-ions.

Determine the Transference Number using the Hittorf's Method.
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.
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.
