Question

what is the equivalent weight of KMnO4 in acidic medium​

Answer 1

Answer:

it will be 31.6

Explanation:

The Mn will go from+7 to +2 in acidic medium hence net decrease in Mn is +5

So equivalent mass =Molar mass/No.of electron gained or loss.

----------->158/5=31.6

Answer 2

In acidic medium equivalent mass of KmNO4 is molecular mass ÷ 5
