Glacial acetic acid has a wide range of applications. In the food industry, it is utilized as a preservative and flavoring agent, while in laboratories, it serves as a crucial reagent in various organic reactions, including esterifications and the preparation of acetyl compounds. Its ability to donate protons makes it useful in acid-base reactions, and its solvent properties allow it to dissolve a variety of organic compounds.

When glacial acetic acid is diluted with water, its pH increases. For instance, a 11 dilution of glacial acetic acid with water results in a pH that may rise above 3, depending on the concentration of the resulting solution. This change occurs because the dilution reduces the concentration of acetic acid molecules and consequently the number of hydrogen ions in the solution, leading to a higher pH and reduced acidity.

This equilibrium indicates that not all acetic acid molecules break apart into acetate ions (CH₃COO⁻) and protons, which is characteristic of weak acids. The degree of ionization of acetic acid is relatively low, leading to its classification as a weak acid. In solution, acetic acid typically has a pH around 2.4 to 3 when concentrated, which reflects its weak acidic nature compared to strong acids.
