<P> Acetic acid / əˈsiːtɪk / , systematically named ethanoic acid / ˌɛθəˈnoʊɪk / , is a colourless liquid organic compound with the chemical formula CH COOH ( also written as CH CO H or C H O ) . When undiluted , it is sometimes called glacial acetic acid . Vinegar is roughly 3 -- 9 % acetic acid by volume , making acetic acid the main component of vinegar apart from water . Acetic acid has a distinctive sour taste and pungent smell . In addition to household vinegar , it is mainly produced as a precursor to polyvinyl acetate and cellulose acetate . It is classified as a weak acid since it only partially dissociates in solution , but concentrated acetic acid is corrosive and can attack the skin . </P>
