How would you distinguish experimentally between an alcohol and a carboxylic acid?
We can experimentally distinguish between an alcohol and a carboxylic acid by reacting with carbonates and hydrogen carbonates. Acid reacts with carbonate and hydrogen carbonate to evolve CO2 gas that turns lime water milky.
Metal Carbonate/Metal Hydrogncarbonate + Carboxylic acid
↓
Salt + Water + Carbon dioxide
Alcohols, on the other hand, do not react with carbonates and hydrogen carbonates.
