1) On addition of carbonates or bicarbonates to an aqueous solution of carboxylic acid, brisk effervescence is observed.
Metal carbonates/Bicarbonates + Carboxylic acid → Salt + Water + Carbon dioxide
Alcohol does not give this test.
2) On addition of sodium metal to alcohol, hydrogen gas is evolved.
2CH3CH2OH + 2Na → 2CH3CH2ONa + H2
Carboxylic acid does not give this test.
