Question

3.0 g of a sample of impure ammonium chloride were boiled
with excess of caustic soda solution. Ammonia gas so evolvedwas passed into 120 ml of N/2 H2SO4. 28 ml of
NaOH were required to neutralise excess of the acid. Calculate the per cent purity of the given sample of ammonium chloride
[Ans. 8296)​

Answer 1

Answer:

Ammonia gas so evolved was passed into 120 mL of N,,2 H_(2)SO_(4). 28 mL of N,,2 NaOH were required to neutralise residual acid. Calculate the percentage
