प्रश्न
How will the action of dilute hydrochloric acid enable you to distinguish between sodium carbonate and sodium sulphite?
उत्तर
Sodium carbonate treated with \[\ce{dil. HCl}\] results in the formation of sodium chloride with the liberation of carbon dioxide gas.
\[\ce{Na2CO3 + 2HCl ⟶ 2NaCl + H2O + CO2 ↑}\]
Sodium sulphite treated with \[\ce{dil. HCl}\] results in the formation of sodium chloride with the liberation of sulphur dioxide gas.
\[\ce{Na2SO3 + 2HCl ⟶ 2NaCl + H2O + SO2 ↑}\]
