Physical properties of acetic acid are:-
• It is a vinegar smelling liquid.
• It is miscible with water in all proportions.
• Ethanoic acid can sour in taste and they has boiling point of 390K and freezes at 290K. Chemical properties of the acetic acid include:-
• Acetic acid reacts with ethyl alcohol in the presence of concentrated sulphuric acid.
This forms esters, giving off a fruity smell.
• On reduction with lithium aluminum hydride, it forms ethanal which is further oxidised to form ethanol.
• Ethanoic acid can react with the metal as
2CH3COOH+2Na=2CH3COONa+H2
