Question

Give the action of acids with carbonates and hydrogen carbonates:

Na₂CO₃ + HCl 🡪

Answer 1

• When acids react with metal carbonates, they will produce salt, and water along with carbon dioxide.
• Carbon dioxide will produce with brisk effervescence.
• Sodium carbonate reacts with hydrochloric acid to form sodium chloride, water, and carbon dioxide.
• The chemical equation for the given reaction is as follows:

$\underset{\mathrm{sodium}\mathrm{carbonate}}{{\mathrm{Na}}_2{\mathrm{CO}}_3\left(\mathrm{aq}\right)}+\underset{\mathrm{hydrochloric}\mathrm{acid}}{2\mathrm{HCl}\left(\mathrm{aq}\right)}\to \underset{\mathrm{sodium}\mathrm{chloride}}{2\mathrm{NaCl}\left(\mathrm{aq}\right)}+\underset{\mathrm{water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}+\underset{\mathrm{carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}$
