Acetic acid is the most commonly used and preferred IUPAC name. The systematic name ethanoic acid, a validIUPAC name, is constructed according to the substitutive nomenclature. The name acetic acid derives from acetum, the Latin word for vinegar, and is related to the word acid itself.
Glacial acetic acid is a name for water-free (anhydrous) acetic acid. Similar to the German name Eisessig (ice-vinegar), the name comes from the ice-like crystals that form slightly below room temperature at 16.6 °C (61.9 °F) (the presence of 0.1% water lowers its melting point by 0.2 °C).
Appearence:-
Colourless transparent liquid; Pungent odor,miscible with water,alcohol,ether and carbon tetrachloride; insoluble in carbon disulfide.
