Description
Purpose
Its primary purpose derives from its weak acidity (pKa 4.76) enabling reactions like esterification salt formation with bases and corrosion of certain metals while acting as a solvent and preservative. Hydrogen bonding causes dimer formation in vapor a
General Description
Acetic acid with the formula CH3COOH is a colorless liquid carboxylic acid known for its sharp vinegar-like odor. It has a density of 1.05 gcm melting point of 16.6C (freezing below this forms glacial acetic acid) boiling point of 118C and is fully miscible with water ethanol and ether.
