Question

Statement 1: The same mass of KMn O 4 ​ corresponds to different numbers of g-equivalents in acidic and alkaline media. Statement 2: The n-factor of KMn O 4 ​ depends on the medium of the reaction in which it is reduced.

I is correct: g-eq = (mass/M) x n , and n is 5 in acid (Mn → +2) but 1 in strong base (Mn → +6), so the same mass gives different g-eq. II is correct and is exactly the reason - the medium fixes the reduction product and hence the n-factor. II explains I, so (a).
