Question

After electrlysis of `NaCI` solution with inert electrodes for a certain period of time `600mL` of the solution was left. Which was found to be `1N` in `NaOH`. During the same time, `31.75 g` of `Cu` deposited in the copper voltameter in series the electrolytic cell. calculate the percentage yield of `NaOH` obtained.

Answer 1

Equivalent mass of `NAOH =40`
Amouunt of `NAOH` formed `=40/1000xx600=24 g`
`31.75 g` of `Cu=1 g`-equivalent of `Cu`.
During the same period, 1 g-equivalent of `NaOH` should have been formed.
1 g-equivalent of `NaOH = 40 g`
% yield `=24/40xx100=60`
