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