Safety is another significant area where glacial and normal acetic acid diverge. Glacial acetic acid is classified as a corrosive substance and can cause severe burns upon contact with skin or eyes. It requires careful handling with appropriate personal protective equipment (PPE), such as gloves and goggles. Normal acetic acid, being significantly diluted, poses much less risk, though it can still cause irritation at higher concentrations, which is why caution is advised in its usage.

The density of glacial acetic acid is approximately 1.05 g/ml at room temperature (around 20°C). This means that one milliliter of glacial acetic acid weighs about 1.05 grams. This property allows chemists and engineers to accurately measure and mix solutions, ensuring that their reactions proceed under controlled conditions. The density of glacial acetic acid can slightly vary depending on temperature, pressure, and purity, but the 1.05 g/ml figure is used as a standard reference.

In addition to its direct applications, the pKa of glacial acetic acid can also be utilized in analytical chemistry. Techniques such as titration and spectrophotometry often rely on knowledge of acid dissociation constants to determine concentrations and reactant behavior in various solutions.

One of the most prominent uses of glacial acetic acid is in the production of chemicals. It acts as a crucial precursor in the manufacture of various organic compounds, such as acetic anhydride and acetate esters. Acetic anhydride, used in the production of synthetic fibers, plastics, and pharmaceuticals, is essential in the industrial sector. Acetate esters, on the other hand, serve as solvents and are widely used in paints, coatings, and adhesives.
