Silver is removed electrolytically from ...

Silver is removed electrolytically from `200mL` of a `0.1N` solution of `AgNO_(3)` by a current of `0.1A`. How long will it take to remove half of the silver from the solution ?

A

`0.1s`

B

`100s`

C

`965s`

D

`9650s`

Verified by Experts

The correct Answer is:

d

`mmol esAgNO_(3)=0.1xx200=20`
`Ag^(o+)+e^(-) rarr Ag`
For `50%` electrolysis, `10mF` is required
`implies 10mF=(It)/(96500)impliest=9650s`
