Acetic acid, also known as acetic acid, is an organic compound with the chemical formula CH3COOH. It is an organic monobasic acid and the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid with a freezing point of 16.6 ℃ (62 ℉). After solidification, it becomes colorless crystals. Its aqueous solution is weakly acidic and highly corrosive, with strong corrosiveness to metals. Steam has irritating effects on the eyes and nose.
