An electrolyte cell contains a solution ofAg2SO4and have platium electrodes. A current is passed until 1.6 g ofO2has been liberated at anode. The amount of silver deposited at cathode would be

Options:

Answer:
D
Solution:

O2--2e→12O2
Equivalent weight of oxygen=162=8
8gO2=1g equivalent
1.6 gO2=168=0.2g equivalentO2
1 g equivalent of Ag = 108 g Ag
0.2 g equivalent of Ag =0.2×108g Ag
= 21.60 g Ag
