What happens when sodium carbonate solution is added to dilutehydrochloric acid?(Write balanced chemical equation only

When sodium carbonate (Na₂CO₃) solution is added to dilute hydrochloric acid (HCl), a chemical reaction occurs, resulting in the formation of sodium chloride (NaCl), water (H₂O), and carbon dioxide (CO₂) gas. This reaction is a classic acid-base reaction where the carbonate ion reacts with the hydrogen ions from the acid.

Balanced Chemical Equation:

$\text{Na}_2\text{CO}_3(aq) + 2 \text{HCl}(aq) \rightarrow 2 \text{NaCl}(aq) + H_2O(l) + CO_2(g)$

Explanation:

In this reaction, sodium carbonate acts as a base and reacts with hydrochloric acid, which is an acid. The carbonate ion (CO₃²⁻) reacts with the hydrogen ions (H⁺) from the hydrochloric acid to release carbon dioxide gas, which can be observed as bubbles during the reaction. The sodium ions (Na⁺) pair with the chloride ions (Cl⁻) to form sodium chloride, which remains dissolved in the aqueous solution. The presence of water is a result of combining hydrogen ions with hydroxide ions (from the dissociation of the carbonate). This overall process is a neutralization reaction that effectively balances the acidic solution with a basic one.
