प्रश्न
State your observation of the following case:
When dilute hydrochloric acid is added to sodium carbonate crystals.
उत्तर
Sodium carbonate crystals reacting with dilute \[\ce{HCl}\] form sodium chloride, water and carbon dioxide, which evolve with brisk effervescence. This is a neutralisation reaction, as sodium carbonate is a basic salt, while hydrochloric acid is an acid.
The chemical equation for this reaction is as follows:
\[\ce{Na2CO3 + 2HCl -> 2NaCl +H2O + CO2 ^}\]
