Answer :

Final answer:

When hydrochloric acid solution is mixed with sodium bicarbonate solution, it forms sodium chloride (salt) and carbon dioxide gas.


Explanation:

Hydrochloric acid (HCl) reacts with sodium bicarbonate (NaHCO3) to form sodium chloride (NaCl) (a salt) and carbon dioxide (CO2) gas, along with water (H2O). The balanced chemical equation for this reaction is:

HCl (aq) + NaHCO3 (aq) → NaCl (aq) + CO2 (g) + H2O (l)
