Glacial acetic acid is composed primarily of carbon (C), hydrogen (H), and oxygen (O) atoms, reflecting its status as a simple carboxylic acid. The molecular structure consists of a methyl group (CH₃) and a carboxyl group (COOH). This fundamental arrangement is responsible for its acidic properties and its wide-ranging reactivity. In terms of its composition by weight, glacial acetic acid is approximately 60% carbon, 10% hydrogen, and 30% oxygen.

Glacial acetic acid refers to the pure, undiluted form of acetic acid. Its name derives from the fact that this compound can solidify into a crystalline form at low temperatures, resembling ice. Characteristically, glacial acetic acid is a colorless liquid with a boiling point of 118.1 °C (244.58 °F) and a melting point of approximately 16.6 °C (61.88 °F). It is a potent solvent and a vital chemical reagent used in the synthesis of various organic compounds.

The relatively high refractive index of glacial acetic acid compared to water (which has a refractive index of about 1.333) signifies its density and molecular interactions. These interactions can have significant implications in various applications, particularly in organic chemistry and photonics.

Moreover, glacial acetic acid finds application in the textile industry, where it is used in dyeing and finishing processes. It also appears in the production of photographic films, where it plays a role in the stabilization of certain chemicals.
