When an aqueous solution of `LiCl` is electrolyzed using graphite electrodes, as the current flows, the `pH` of the solution around cathode `……………………`

Text Solution

Verified by Experts

The correct Answer is:

(Increaese)

( Increases )

Due to the formation of `overset(c-)(O)H` ions at cathode, `pOH` decreases and `pH` increases.
