Which of the following half-reactions should be affected by the change in H⁺ concentration:
(i) ClO₂^-(aq) + H₂O(l) + 2e^- → ClO^-(aq) + 2OH^-(aq)
(ii) MnO₂(s) + 4H⁺(aq) +2e^- → Mn²⁺(aq) + 2H₂O(l)
(iii) ½ Cl₂(aq) + e^- → Cl^-(aq)

Question

Quizplus · Accepted Answer

The change in H+ concentration affects reactions where H+ is a reactant or product. Reaction (i) does not explicitly involve H+, while reaction (ii) does, indicating it would be affected by changes in H+ concentration. Reaction (iii) does not involve H+ at all.
