108 g fairly concentrated solution of `AgNO_(3)` is electrolysed by using 0.1 F charge the mass of resulting solution is
(a)94g
(b)11.6g
(c)96.4g
(d)None of these

A

94 g

B

11.6 g

C

96.4 g

D

none

Text Solution

Verified by Experts

The correct Answer is:
C
At anode
`2HgO(l)to4H^(+)(aq)+O_(2)(g)+4e^(-)`
At cathode
`Ag^(+)(aq)+e^(-)toAg(s)`
Ag deposited out `=0.1mol e=10.8gram`
`O_(2)` expelled out `=(0.1)/(4)=0.8gram`
total wt. loss of the solution =11.6 gram
wt. of remaining solution `=108-11.6=96.4gram`
