Question
Distinguish between the given pair of compounds using the test given within brackets:
Sodium nitrate and sodium sulphite (using dilute sulphuric acid).
Advertisements
Solution
Sodium sulphite reacts with dilute H2SO4 to produce SO2 gas.
\[\ce{Na2SO3 + H2SO4 -> Na2SO4 + H2O + SO2 ^}\]
Sodium nitrate does not react with dilute H2SO4, so no gas is evolved.
\[\ce{NaNO3 + dil. H2SO4 -> No visible reaction}\]
