For the reaction , which of the following is/are correct? — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**(A/B/C)** According to Nernst equation: $E = E^o - \frac{0.059}{5} \log \frac{[Mn^{2+}]}{[MnO_4^-][H^+]^8}$. As $[H^+]$ increases (pH decreases), $E$ increases, making it a stronger oxidant. <br>**(D)** $n$-factor changes: 5 in acidic, 3 in neutral/weakly alkaline, 1 in strongly alkaline.
