Question
State your observation in given case When dilute hydrochloric acid is added to sodium carbonate crystals
Solution
Sodium carbonate crystals on reaction with dilute HCl forms sodium chloride, water, and carbon dioxide gas, which is evolved with brisk effervescence. This is a neutralization reaction as sodium carbonate is a basic salt, while hydrochloric acid is an acid. The chemical equation for this reaction is as follows:
Na2CO3 + 2HCl → 2NaCl +H2O + CO2
