When, during electrolysis of a solution ...

When, during electrolysis of a solution of `AgNO_(3) 9650` colombs of charge pass through the electroplating path, the mass of silver deposited on the cathode will be:

A

`21.6 g`

B

`108 g`

C

`1.08g`

D

`10.8g`

Text Solution

Verified by Experts

The correct Answer is:
D
No. of equivalents of Ag deposited `=(Q)/(F)`
`=(9650)/(96500) =(1)/(10)`
No. of equivalents `= (wt)/(Eq.wt) = (1)/(10)`
`:. (wt)/(108) = (1)/(10)`
`:. Wt = 10.8 g`
