प्रश्न
How will the action of dilute hydrochloric acid on sodium carbonate and sodium sulphite enables you to distinguish between these two compounds?

उत्तर
Sodium carbonate + hydrochloric acid = sodium chloride + water + carbon dioxide
\[\ce{NaCO3 + HCl -> NaCl + H2O + CO2}\]
Sodium sulphite + hydrochloric acid -> sodium chloride + water + hydrogen sulphide
\[\ce{2Na2SO3+ 4HCI -> 4NaCI + 6H2O + 2H2S}\]
Production of Foul smelling hydrogen sulphide gas will easily help to distinguish between sodium carbonate and sodium sulphite.
