Acetic acid at room temperature have a strong pungent smell is a colorless liquid. Acetic acid melting point of 16.5 ℃ (289.6 K). Boiling point 118.1 ℃ (391.2 K). The relative density of 1.05, flash point 39 ℃, explosion limit 4% ~ 17% (volume). Below the melting point of pure acetic acid will freeze ice crystals shaped crystals, so anhydrous acetic acid, also known as glacial acetic acid. Acetic acid soluble in water and ethanol, its aqueous solution weak acidity. Acetate is also soluble in water.

[Edit this paragraph] Chemical Properties
Acid
Carboxylic acid, such as acetic acid, the carboxyl group can be part of the ionized hydrogen atoms into hydrogen ions (protons) and released, resulting in carboxylic acid. Acetic acid in aqueous solution is one dollar weak acid, the acidity coefficient of 4.8, pKa = 4.75 (25 ℃), the concentration of 1mol / L acetic acid solution (similar to the concentration of domestic vinegar), pH 2.4, meaning that only 0.4% of the Dissociation of acetic acid molecules.
It prompted the acidity of acetic acid with sodium carbonate, cupric hydroxide, phenol and sodium reaction to a substance.
2CH3COOH + Na2CO3 = 2NaCH3COO + CO2 ↑ + H2O
2CH3COOH + Cu (OH) 2 = Cu (CH3COO) 2 + 2H2O
CH3COOH + C6H5ONa = C6H5OH (phenol) + CH3COONa
