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.
\[\ce{Na2CO3 + 2HCl -> 2NaCl +H2O + CO2 ^}\]
