108 g solution of `AgNO_(3)` is electrolysed using Pt electrodes by passing a charge of 0.1 F. The mass of resultant solution left is :

A

98g

B

107.2g

C

11.6g

D

`96.4g`

Text Solution

Verified by Experts

The correct Answer is:
D
`Ag^(+)+ e^(-)rightarrow Ag`
`2OH ^(-)rightarrow H_(2)O + (1)/(2)O_(2)+ 2e^(-)`
`therefore Eq`.of `Ag^(+)` lost= 0.1= eq. of `O_(2)` formed and escaped
Total mass loss `= 0.1xx108 + (0.1xx32)/(4) = 11.6`
