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")=18/8g=0.2`
So, number of gram equivalent of Ag deposited = 0.2
Amount of Ag deposited
= Gram equivalent `xx` Equivalent
=0.2 Equivalent `xx` 108 g Equivalen`t^(-1)`=21.6 g
