Acetic acid, known chemically as CH₃COOH, presents itself in various forms, one of which is glacial acetic acid. The term glacial refers to its pure, undiluted state, where it appears as a colorless liquid at room temperature. This article explores the formula of glacial acetic acid, its properties, and its various applications.

The density of glacial acetic acid is approximately 1.05 g/cm³ at 20 °C (68 °F). This makes it denser than water, which has a density of about 1.0 g/cm³. This property is significant in applications involving separation processes where the density of solutions is a crucial factor. Furthermore, glacial acetic acid has a relatively high viscosity compared to water, which influences its flow characteristics and handling in industrial processes. The viscosity can affect the mixing and reaction rates when used in chemical reactions.

Moreover, glacial acetic acid plays a crucial role in the manufacture of specialty chemicals, such as acetic anhydride, which is used in the production of cellulose acetate, a plastic material commonly used in photographic films and eyeglass frames. The acid is also utilized in the textile industry for dye and finishing, as well as in the production of adhesives and coatings.
