Question

for preparation of one litre of N/10 H2SO4 solution we need H2SI4 equal to

Answer 1

Answer: 4.9gm

Explanation:

you require a N/10 solution i.e.0.1 Normal solution .

Normality= Molarity×Basicity

As basicity of H2SO4 is 2, so

1 Molar soluation of H2SO4 is equal 2 N solution

molecular weight of H2SO4= 98 gms

for 1 M solution you would require 98 gms = 2 N solution

1 N solution of 1 litre would require 98/2 = 49 gms

for a 0.1 N solution = 4.9 gms
