Physical properties
- It is a colourless and pungent smelling liquid.
- Its melting point is 290K so it often freezes during winter and looks like glacier. Therefore, it is also known as glacial acetic acid.
- It is soluble in water in all proportions.
- 5% to 8% solution of Ethanoic acid in water is called vinegar.
Chemical properties
Reaction with alcohol:
Ethanoic acid reacts with ethanol in the presence of an acid to give ester.
Ethanoic acid reacts with ethanol in the presence of an acid to give ester.
- CH2COOH + C2H5OH = CH3COOC2H5 + H2O
Reaction with base:
Ethanoic acid reacts with sodium hydroxide to give sodium ethanoate (sodium acetate)and water.
Ethanoic acid reacts with sodium hydroxide to give sodium ethanoate (sodium acetate)and water.
- CH3COOH + NaOH = CH3OONa + H2O
Reaction with carbonates and bicarbonates:
Ethanoic acid reacts with carbonates and bicarbonates to give salt , carbon dioxide and water.
