Question

An aqueous solution of CuSO4 is subjected to electrolysis using inert electrodes. The pH of the solution will (A) decrease (B) increase or decrease depending on the strength of the current. (C) increase (D) remains unchanged

At cathode: Cu(aq)2++2e- → Cu(s) At anode: 2H2O → O2 +4H++4e- Production of H+ ions will decrease pH.

decrease

increase or decrease depending on the strength of the current.

increase

remains unchanged

$A t c a t h o d e : C u_{(a q)}^{2 +} + 2 e^{-} \to C u_{(s)}$
$A t an o d e : 2 H_{2} O \to O_{2} + 4 H^{+} + 4 e^{-}$
Production of $H^{+}$ ions will decrease pH.
