An electrolytic cell contains aqueous solution of silver sulphate and has platinum electrons. A current is passed until 1.6 g of oxygen has been liberated at the anode. The amount of silver deposited at the cathode would be

A

107.88 g

B

1.6 g

C

0.8 g

D

21.58 g

Text Solution

Verified by Experts

The correct Answer is:
D
Number of gram equivalent of `O_2` liberated = Weight / Equivalent weight = 16/8 g = 0.2
So, number of gram equivalent of Ag deposited = 02
Amount of Ag deposited = Gram equivalent x Equivalent weight = 0.2 Equivalent x 108 g `"Equivalent"^(-1)` = 21.6g
