Acetic acid, also known as ethanoic acid and methanecarboxylic acid, is a colorless liquid that has a strong and distinct pungent and sour smell. Its chemical formula is C2H4O2: it has two carbon (C) atoms, four hydrogen (H) atoms and two oxygen (O) atoms.t is an organic compound that is classified as a carboxylic acid because a carboxyl (-COOH) group is present in its chemical structure. Acetic acid is also known as the second simplest carboxylic acid.
Acetic acid /ÉËsiËtÉ¨k/ , systematically named ethanoic acid /ËÉÎ¸ÉËnoÊÉ¨k/ , is an organic compound with the chemical formula CH 3 COOH (also written as CH 3 CO 2 H or C 2 H 4 O 2).It is a colourless liquid that when undiluted is also called glacial acetic acid.lacial 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 Â°C (61.9 Â°F) (the presence of 0.1% water lowers its melting point by 0.2 Â°C).
