Answer

When a cold and concentrated solution of sodium chloride (NaCl) reacts with ammonia (NH₃) and carbon dioxide (CO₂), it leads to the formation of sodium bicarbonate (NaHCO₃) and ammonium chloride (NH₄Cl). This reaction is often used in the preparation of these compounds.

The balanced chemical equation for this reaction is:

NaCl (aq) + NH₃ (g) + CO₂ (g) + H₂O (l) → NaHCO₃ (s) + NH₄Cl (aq)
