When acidulated water (dil.H2SO4 solution)


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


Anode: 2H2O(l)ā†’ O2(g) + 4H+ (aq) + 4eā€“

Cathode: 4H+ + 4e-ā†’ 2H2

Overall cell reaction: 2H2O(l) ā†’ O2(g) + 2H2(g)

pH remains the same because concentration of H+ ions remains constant.
