Here's why:
* Reaction: When sodium carbonate reacts with hydrochloric acid, it undergoes a neutralization reaction to produce carbon dioxide gas (CO₂), water (H₂O), and sodium chloride (NaCl).
Chemical Equation:
Na₂CO₃ (s) + 2HCl (aq) → 2NaCl (aq) + H₂O (l) + CO₂ (g)
* Solubility: Sodium chloride (NaCl) is soluble in water, and carbon dioxide gas is released. This leaves a clear solution containing dissolved sodium chloride.
In simpler terms: The hydrochloric acid reacts with the sodium carbonate, breaking it down and forming substances that are soluble in water.
