Question:

1C electricity deposits: 10.8 g of Ag

96500 g of Ag

10.8 g of Ag

half of electrochemical equivalent of Ag

electrochemical equivalent of Ag

Solution:

The correct option is B electrochemical equivalent of Ag
From Faraday's first law,
w=Z×Q
When Q=1 C
Z=108/1=108
w=Z
Where Z=electrochemical equivalent of Ag.
Hence, option B is correct.
