About Acetic Acid

Acetic Acid

Acetic acid, systematically named ethanoic acid is an organic compound with the chemical formula CH₃COOH (also written as CH₃CO₂H or C₂H₄O₂). It is a colourless liquid that when undiluted is also 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. 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.
