Question

(a) Define equivalent mass of an oxidising agent. 

(b) How would you calculate the equivalent mass of potassium permanganate?

Answer 1

(a) The equivalent mass of an oxidizing agent is the number of parts by mass which can furnish 8 parts by mass of oxygen for oxidation.

(b) Potassium permanganate is an oxidizing agent.

80 parts by mass of oxygen are given by 316 g of KMnO₄ . 

\(\therefore\)  8 parts by mass of oxygen will be furnished by 316/80 x 8 = 31.6 

Equivalent mass of KMnO₄ = 31.6 g eq^-1
