Acetic acid, which is also known as ethanoic acid, has a chemical formula of C2H4O2. The concentrated form at 99.5% is typically referred to as glacial acetic acid because it can solidify at low temperatures. This high concentration results in a more potent acidic solution, making it an invaluable reagent in various chemical processes. The compound has a boiling point of 118 °C and a freezing point of 16.6 °C, which allows it to be handled in various temperature ranges. Its ability to act as both an acid and a solvent underlines its versatility.

2. Corrosion Inhibition Glacial acetic acid can also be used in corrosion inhibition applications. By serving as a medium that contains inhibitors, it can help protect metals in electrochemical environments. The acetate ion forms a passive layer over the metal surface, thereby reducing the rate of corrosion in various industrial applications.

Regulatory bodies such as the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) established guidelines to mitigate the risks associated with glacial acetic acid. These standards encompass permissible exposure limits, recommended safety measures, and the use of specific PPE to minimize the likelihood of accidents and health issues among workers.
