Alternative definition of the noun acetic acid


  1. [organic compound] A clear colourless organic acid, CH3COOH, formed by the oxidation of ethanol; it is used as a solvent and has very many industrial applications; it is the major acidic component of vinegar.


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. Vinegar is roughly 3%-5% 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. Besides its production as household vinegar, it is mainly produced as a precursor to polyvinylacetate and cellulose acetate. Although it is classified as a weak acid, concentrated acetic acid is corrosive and can attack the skin.
