How can ethanol and ethanoic acid be differentiated on the basis of their physical and chemical properties?

Answer:

The difference between the ethanol and ethanol and ethanoic acid depending on their physical and chemical properties are given below in the table.

Ethanol

Ethanoic acid

At room temperature, Ethanol is always a liquid, and it has a melting point of 156K and a boiling point of 351 K.

Ethanoic acid is also referred to as glacial acetic acid because its melting point is 16oC. it often freezes in the winter season when the climate is cold.

Ethanol has a pleasant odour

Ethanoic acid has a vinegar-like smell.

Ethanol does not react with carbonates or hydrogen carbonate.

CH3CH2OH + Na2CO3→ Noreaction

Ethanoic acid reacts with sodium bicarbonate as shown in the reaction below

CH3COOH + NaHCO3 → CH3COONa + H2O + CO2
