A current strength of `1.0A` is passed for `96.5 s` through `100mL` of a solution of `0.05 M KCl`. The concentration of the final solution with respect to `overset(c-)(O)H` ions is

A

`0.005M`

B

`0.05M`

C

`0.01M`

D

`0.001M`

Text Solution

Verified by Experts

The correct Answer is:
c
Aqueous `KCl` on electrolsysi gives `Cl_(20` at anode and `H_(2)` at cathode and `overset(c-)(O)H` ions in the solution.
Equivalent of current `=(1xx96.5)/(96500)=0.001Eq-=1mEq`
`:. [overset(c-)(O)H]=(1mEq)/(100mL)=0.01M`
