Best answer

Alcohols can be distinguished from carboxylic acid using the sodium carbonate (Na2CO3) or sodium bicarbonate (NaHCO3) test. Alcohols do not react with sodium carbonate or bicarbonate, whereas acid reacts with them to release carbon dioxide.

2RCOOH + Na2CO3→ 2RCOONa + CO2↑ + H2O

RCOOH + NaHCO3→ RCOONa + CO2↑ + H2O

Alcohol + Na2CO3→ No reaction
