How will the action of dilute hydrochloric acid enable you to distinguish between sodium thiosulphate and sodium sulphite?

उत्तर
Sodium thiosulphate reacts with dil. HCl to produce sulphur dioxide gas and precipitates yellow sulphur.
\[\ce{Na2S2O3 + 2HCl → 2NaCl + H2O + SO2 + S↓}\]
Sulphur is not precipitated when sulphites are treated with dil. HCl.
\[\ce{Na2SO3 + 2HCl -> 2NaCl + H2O + SO2 ^}\]
