Acetic acid facts

Acetic acid is a colorless liquid with a sharp, vinegar-like smell, and it is a weak carboxylic acid.
Vinegar is typically about 4 to 8 percent acetic acid in water, and the pure acid is used to make vinyl acetate, cellulose acetate, and other chemicals.
Pure acetic acid freezes at about 17 °C, so it can form ice-like crystals in a cool room, which is why it is called glacial acetic acid.
