Acetic acid is an organic compound with the chemical formula CH3COOH. It is a colourless liquid that when undiluted is also called glacial acetic acid. As the main component of vinegar, it has a distinctive sour taste and pungent smell. Although it is classified as a weak acid, acetic acid is highly dangerous to skin.
