Question

Give the action of dilute acids on metal carbonates:

Na₂CO₃ + H₂SO₄ 🡪

Answer 1

• When acids react with metal carbonates, they form salt, carbon dioxide, and water.
• Carbon dioxide gas will produce with brisk effervescence.
• When sodium carbonate reacts with dilute sulphuric acid, it will form sodium sulfate, carbon dioxide, and water.
• The chemical equation for the given reaction is as follows:

$\underset{\mathrm{sodium}\mathrm{carbonate}}{{\mathrm{Na}}_2{\mathrm{CO}}_3\left(\mathrm{s}\right)}+\underset{\mathrm{sulphuric}\mathrm{acid}}{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}\to \underset{\mathrm{sodium}\mathrm{sulphate}}{{\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}+\underset{\mathrm{carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$
