- Ethanoic acid is a weak monoprotic acid. As such, its chemical properties are similar to acids such as hydrochloric acid, nitric acid and sulphuric acid.
- Ethanoic acid can react with:
- metal carbonate
Reactions of Carboxylic Acids with Reactive MetalsCarboxylic acids react with the more reactive metals to produce a salt and hydrogen.
Carboxylic Acid + Reactive Metal → Salt + H2Example:
CH3COOH + Zn → Zn(CH3COO)2 + H2
CH3COOH + Ca → Ca(CH3COO)2 + H2
HCOOH + Mg → Mg(HCOO)2 + H2
Reactions of Carboxylic Acids with CarbonatesAs other acids, carboxylic acids react with carbonate metal to produce a salt, water and carbon dioxide.
Carboxylic Acid + Metal Carbonate → Salt + Carbon Dioxide + Water
HCOOH + Na2CO3 → HCOONa + CO2 + H2O
CH3COOH + CaCO3 → Ca(CH3COO)2 + CO2 + H2O
NeutralisationAs other acids, carboxylic acids react with base oxide or alkali to produce salt and water.
Carboxylic Acid + Base Oxide/Alkali → Salt + Water
HCOOH + CaO → Ca(HCOO)2 + H2O
CH3COOH + NaOH → CH3COONa + H2O
CH3COOH + Al2O3 → Al(CH3COO)3 + H2O
EsterificationCarboxylic acid reacts with alcohol with the presence of .concentrated sulphuric acid as catalyst to produce ester and water.
Carboxylic Acids + Alcohol → Ester + Water
CH3COOH + C2H5OH → CH3COOC2H5 + H2O
CH3COOH + CH3OH → CH3COOCH3 + H2O
