* Sodium chloride (NaCl): This is a common salt, also known as table salt.
* Carbon dioxide (CO₂): A colorless, odorless gas.
* Water (H₂O): A liquid.
Here's the balanced chemical equation:
Na₂CO₃ (aq) + 2HCl (aq) → 2NaCl (aq) + CO₂ (g) + H₂O (l)
Explanation:
* The sodium carbonate reacts with the hydrochloric acid, exchanging ions.
* Sodium (Na⁺) from the carbonate combines with chloride (Cl⁻) from the acid to form sodium chloride.
* The hydrogen ions (H⁺) from the acid react with the carbonate ions (CO₃²⁻) to form carbonic acid (H₂CO₃).
* Carbonic acid is unstable and quickly decomposes into carbon dioxide and water.
This reaction is also characterized by the release of heat, making it an exothermic reaction. The bubbling you see is due to the release of carbon dioxide gas.
