When acidulated water (dil.H2SO4 solution) is electrolysed, will the pH of the solution be affected? Justify your answer.

Reaction on Anode – 2H2O(l)→ O2(g) + 4H+ (aq) + 4e–

Reaction on Cathode – 4H+ + 4e-→ 2H2

Complete Reaction:

2H2O(l) → O2(g) + 2H2(g)

The pH will not be affected and stays the same.
