Acetic Acid 99.5% Glacial 乙酸 醋酸

Acetic acid, or ethanoic acid, is a colourless liquid organic compound with the chemical formula CH3COOH.
Concentration: 99.5%

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.
