Question

Normality of an aqueous solution containing HCl and
H2SO4 is 0.2 N. When 10 mL of this solution is treated
with excess of AgNO, solution, 0.1435 gram of AgCl
precipitate is obtained. Calculate the concentration of
each acid in gram/litre.​

Answer 1

Answer

Correct option is

A

0..1 N

AgNO

36.5⟶143.5

(x)⟵0.1435

x=

143.5

0.1435×36.5

=0.0365 grams

Basicity of HCl is 1. So Molarity = Normality
