Question

247. Action of dilute acids on metal hydrogen carbonates:

(c) NaHCO₃ + H₂SO₄ 🡪

Answer 1

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

$\underset{\mathrm{Sodium}\mathrm{hydrogen}\mathrm{carbonate}}{2{\mathrm{NaHCO}}_3}+\underset{\mathrm{Sulfuric}\mathrm{acid}}{{\mathrm{H}}_2{\mathrm{SO}}_4}🡪\underset{\mathrm{Sodium}\mathrm{sulfate}}{{\mathrm{Na}}_2{\mathrm{SO}}_4}+\underset{\mathrm{Carbon}\mathrm{dioxide}}{2{\mathrm{CO}}_2}+\underset{\mathrm{Water}}{3{\mathrm{H}}_2\mathrm{O}}$
