How will the pH of brine (aq. NaCl solution) be affected when it is electrolyzed?

Answers (1)

Upon electrolysis of Brine solution, the following reactions take place:

Cathode :2H^{+}+2e^{-}\rightarrow H_{2}

Anode : 2Cl^{-}\rightarrow Cl_{2}+2e^{-}

The remaining Na^{+} and OH^{-} ions are responsible for turning the solution basic and thus increase the pH.
