Question

In neutral solution, equivalent mass of KMnO₄ is ______ of its molecular mass.

Answer 1

In neutral solution, equivalent mass of KMnO₄ is one-third of its molecular mass.

Explanation:

In neutral medium, 1 mole of KMnO₄ accepts 3 electrons as it gets reduced from Mn⁷⁺ to Mn⁴⁺ (MnO₂). So, the equivalent mass = molecular mass ÷ 3.
