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