Acetic acid glacial, often simply referred to as glacial acetic acid, is a highly concentrated form of acetic acid. Unlike ordinary vinegar which contains only about 5% acetic acid, this industrial-grade chemical is composed of at least 99% acetic acid. Its name comes from its physical appearance; it is a clear, colorless liquid that resembles frozen water or 'glacier' due to its high purity.

The composition of glacial acetic acid is straightforward yet profound. As a simple carboxylic acid, it comprises a methyl group (CH₃) attached to a carboxyl group (COOH). This functional group is responsible for the acidic properties of the compound, allowing it to donate protons (H⁺) in solution. The high purity of glacial acetic acid distinguishes it from diluted vinegar, which contains approximately 4-8% acetic acid and is far less potent. Due to its strong and concentrated nature, glacial acetic acid has a storied history in various chemical processes and industrial applications.

Glacial acetic acid, chemically known as ethanoic acid, is a clear, colorless liquid with a pungent odor and is widely used in various industrial and laboratory applications. As a highly concentrated form of acetic acid, it contains approximately 99% acetic acid and is known for its corrosive nature. Therefore, it is crucial to understand the safety implications associated with glacial acetic acid, which is detailed in its Safety Data Sheet (SDS).
