Define equivalent mass of an oxidising agent How would you calculate the equivalent mass of potassium permanganate?

Answer»

SOLUTION :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
Potassium permanganate is an oxidizing agent.
`2KMNO_(4)+3H_(2)SO_(4)rarrK_(2)SO_(4)+2MnSO_(4)+3H_(2)O+5[O]`
80 parts by mass of oxygen are given by 316 g of `KMnO_(4)`
8 parts by mass of oxygen will be FURNISHED by `316/80 XX 8=31.6`
Equivalent mass of `KMnO_(4)=31.6 g eq^(-1)`
