Sulphuric acid can be used to prepare a number of gases in the laboratory. Write balanced equations for the reactions from which the following gases are obtained, using dilute sulphuric acid as one of the reactants:
(i) Hydrogen
(ii) Carbon dioxide
(iii) Sulphur dioxide

Open in App

Solution

Given below are the balanced chemical reactions involving dilute sulphuric acid, whereby, the following gases are produced:

(i) Hydrogen gas is evolved on reaction with metals:

M + H₂SO₄ → MSO₄ + H₂

(ii) Metal carbonates evolve carbon dioxide:

MCO₃ + H₂SO₄ → MSO₄ + H₂O +CO₂

(iii) Metal sulphites and metal bisulphite release sulphur dioxide:

M₂SO₃ + H₂SO₄ → M₂SO₄ + H₂O +SO₂
2MHSO₃ + H₂SO₄ → M₂SO₄ + 2H₂O + 2SO₂

(where, M is any metal)
