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

1. Ethanol is a liquid at room temperature with a pleasant odour while ethanoic acid has a vinegar-like smell.
2. The melting point of ethanol is 156^oK, while the melting point of ethanoic acid is 17$°$C and hence it often freezes during winter in cold climates.
3. Ethanoic acid reacts with metal carbonates and metal hydrogen carbonates to form a salt, water, and carbon dioxide gas while ethanol does not react with metallic carbonates.
