One of the most notable applications of acetic acid is in pickling. The process of pickling vegetables involves immersing them in a solution of acetic acid, salt, and water. This method not only imparts a tart flavor but also creates an environment that inhibits the growth of spoilage microorganisms. The acidity of acetic acid lowers the pH of the food, making it less hospitable for harmful bacteria, thus extending the shelf life of the pickled products.

Moreover, glacial acetic acid plays a role in laboratory settings as a reagent in chemical reactions and analytical studies. It is commonly used in titrations, a method to determine the concentration of a solution, thanks to its acidic properties. Furthermore, its ability to dissolve various organic compounds makes it a valuable solvent in organic synthesis, facilitating the creation of pharmaceuticals and other chemical products.

Density is defined as the mass of a substance per unit volume. For liquids, it is commonly expressed in grams per milliliter (g/ml). The density of glacial acetic acid at room temperature (around 20 °C) is approximately 1.05 g/ml. This density indicates that glacial acetic acid is denser than water, which has a density of about 1.00 g/ml at the same temperature. This property is essential when considering the mixing of glacial acetic acid with other substances and predicting the outcomes of chemical reactions.
