Hydrochloric Acid and Sodium Acetate
HCl + CH3COONa → CH3COOH + NaCl
Overview
A strong acid reacts with the salt of a weak acid to liberate the weak acid. Hydrochloric acid protonates acetate ions to form acetic acid because HCl is a much stronger acid. This reaction demonstrates the principle that stronger acids displace weaker acids from their salts.
Participants
| Role | Substance | Coefficient | State |
|---|---|---|---|
| Reactant | Hydrochloric Acid HCl | 1 | (aq) |
| Product | Acetic Acid CH₃COOH | 1 | (aq) |
| Product | Sodium Chloride NaCl | 1 | (aq) |
Everyday Example
Adding vinegar (acetic acid) to a solution of baking soda generates the characteristic fizzing because the same displacement principle applies to carbonate salts.
Industrial Importance
This principle is used in industrial chemistry to produce weak acids from their salts and in understanding buffer system behavior when strong acids are added.
