Question

1. Calculate the normality of the follwoing solutions.

a) 1.5M KOH b) 0.3M H₂SO₄ C) 0.35M Ba(OH)₂   d) 1.05M H₃PO₄

Answer 1

a) 1.5M KOH

normality(N) = M*Z

Z= basicity of acids (or) acidity of bases (or)charge of salts = 1

Normality(N) = 1.5*1 =1.5 N

b) 0.3M H₂SO₄

Z= basicity of acids (or) acidity of bases (or)charge of salts = 2

Normality(N) = 1.5*2 = 3 N

C) 0.35M Ba(OH)₂

Z= basicity of acids (or) acidity of bases (or)charge of salts = 2

Normality(N) = 0.35*2 = 0.7 N

  d) 1.05M H₃PO₄

Z= basicity of acids (or) acidity of bases (or)charge of salts = 3

Normality(N) = 1.05*3 = 3.15 N
