Glacial acetic acid is characterized by its pungent odor and its ability to form hydrogen bonds, which gives it a relatively high boiling point compared to other hydrocarbons. With a molecular weight of 60.05 g/mol, it consists of a carboxyl group (-COOH) attached to a methyl group (-CH₃). This makes it a weak acid, capable of donating a proton (H⁺) in a solution. The pKa of acetic acid is approximately 4.76, indicating its weak acidic nature.

Proper storage is also critical to ensure safety. 56% acetic acid should be stored in a cool, well-ventilated area, away from incompatible substances such as strong bases and oxidizers. Containers should be tightly sealed to prevent evaporation of vapors, which can lead to hazardous concentrations in the air.

Glacial acetic acid, a colorless liquid with a distinct vinegar-like smell, is a vital chemical compound widely utilized in various industrial and laboratory applications. Its chemical formula, C2H4O2, reveals that it consists of two carbon atoms, four hydrogen atoms, and two oxygen atoms. One of the key characteristics of glacial acetic acid is its molecular mass, which plays a crucial role in its practical applications and relevance in chemical reactions.
