Statement 1: The number of g-equivalents in the same mass of KMnO₄ is in 5:3:1 ratio in acid, neutral and strong basic medium, respectively.
Statement 2: The oxidation state of Mn changes from +7 state to +2, +4 and +6 states, respectively, in acid, neutral and strong basic medium.
Options:
Answer:
A
Solution:
G-equivalents per mole equal the n-factor. In acid MnO₄⁻ Mn²⁺ (n = 5), in neutral medium MnO₂ (n = 3), in strong base MnO₄²⁻ (n = 1), giving the 5:3:1 ratio - I is correct. II states exactly these oxidation-state changes (+7 to +2, +4, +6), which produce the n-factors 5, 3, 1, so II is correct and explains I. Hence (a).
