Understanding the Water Content in Glacial Acetic Acid

Another important aspect of glacial acetic acid in TAE buffer is its role in preserving the integrity of DNA samples during electrophoresis. Acetic acid is known to have a protective effect on nucleic acids by minimizing the degradation of DNA. This is particularly crucial when working with sensitive samples that may be susceptible to hydrolytic damage or enzymatic degradation. By maintaining a stable and slightly acidic environment, glacial acetic acid helps to shield DNA from degradation, ensuring that samples remain intact for subsequent analytical processes.

The boiling point of glacial acetic acid is approximately 118.1°C (244.58°F). This relatively high boiling point can be attributed to the strong intermolecular forces present in the liquid. Specifically, glacial acetic acid molecules engage in hydrogen bonding with one another, resulting in a more stable liquid structure that requires more energy (in the form of heat) to break these bonds and transition into the gaseous state. Hydrogen bonding arises because of the presence of a hydroxyl (–OH) group in acetic acid, which allows for the interaction between the hydrogen atom of one molecule and the oxygen atom of another.

Individuals who handle glacial acetic acid should use personal protective equipment (PPE) to mitigate exposure risks. Recommended PPE includes
