* Sodium ethanoate (CH₃COONa)
* Carbon dioxide (CO₂) gas
* Water (H₂O)
Here's the balanced chemical equation:
NaHCO₃(aq) + CH₃COOH(aq) → CH₃COONa(aq) + CO₂(g) + H₂O(l)
Explanation:
* Ethanoic acid (CH₃COOH) is a weak acid, donating a proton (H⁺).
* Sodium hydrogencarbonate (NaHCO₃) acts as a base, accepting the proton.
* The proton transfer forms sodium ethanoate (CH₃COONa), which is a salt.
* The remaining hydrogen and carbonate ions combine to form carbon dioxide (CO₂) gas and water (H₂O).
Observations:
* You would observe bubbling as carbon dioxide gas is released.
* The reaction is exothermic, meaning it releases heat, and you might feel the container warm up.
* The solution will become less acidic as the ethanoic acid is consumed.
This reaction is also used in baking to produce carbon dioxide gas, which helps bread and cakes rise. It's also used in some antacids to neutralize stomach acid.
