Question

what will be the normality of 1 M KMnO4 solution​

Answer 1

Answer:

5N

Explanation:

kmno4 1N=.2M so 1M=5N

Answer 2

Given:

Molarity of KMnO₄ = 1M

To Find:

Normality - N =?

Solution:

Formula used:

• Normality = Molarity × n factor

• n factor - acidity or basicity of the substance
• KMnO₄ has different acidity and basicity in acidic, basic, and neutral solutions.

Calculating Normality in acidic Solution of KMnO₄(n = 5; electron transfer is 5)

N = M × n

N = 1 × 5

N = 5 N

Calculating normality in Basic Solution of KMnO₄ (n = 1; electron transfer is 1)

N = M × n

N = 1 × 1

N = 1N

Molarity = Normality in a basic solution of KMnO₄

Calculating normality in Neutral Solution of KMnO₄ (n = 3; electron transfer is 3)

N = M × n

N = 1 × 3

N = 3 N
