Question

249. Treating alkalis with acidic oxides:

(a) $\mathrm{NaOH}+{\mathrm{CO}}_2\to$

Answer 1

• Acidic oxides are non-metal oxides.
• When a base reacts with non-metal oxides, they neutralize each other and form salt and water.
• When Sodium hydroxide reacts with Carbon dioxide, it will form Sodium carbonate and water.
• The Chemical equation for the given reaction is as follows:

$\underset{\mathrm{Sodium}\mathrm{Hydroxide}}{2\mathrm{NaOH}\left(\mathrm{aq}\right)}+\underset{\mathrm{Carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Sodium}\mathrm{Carbonate}}{{\mathrm{Na}}_2{\mathrm{CO}}_3\left(\mathrm{aq}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$
