What is the time (in sec) required to deposit all the silver present in 125 ml of 1 M `AgNO_(3)` solution by passing a current of `241.25` A?

A

2412.5

B

24125

C

4825

D

28250

Text Solution

Verified by Experts

The correct Answer is:
B
Amount of Ag in solution =MxxV (mL)
`=1xx250=250m ` mol
`=250xx10^(-3)` mol
`=250xx10^( -3)` mol
=0.25mol
`Ag^(+)+e^(-)rarrAg`
1 mol 96500C
Reduction of 1 mol of Ag requires 96500C
Reduction of 0.25 mol of Ag requires `=96500xx0.23=24125C`
