Another important use of glacial hydrochloric acid can be found in the food industry, where it is used for food preservation and in the production of gelatin. The acid helps maintain the necessary pH levels in various food products, thereby restricting the growth of bacteria and prolonging shelf life.

Moreover, glacial acetic acid contributes to the visualization and staining of the separated molecules. After the electrophoresis, the gel is often stained with ethidium bromide, a fluorescent dye. Acetic acid can be used to destain the gel, removing excess dye and enhancing the contrast between the stained bands and the background, making it easier to interpret the results.

Glacial acetic acid, a colorless liquid with a distinctive pungent odor, is an important chemical in various industries and laboratories. Its chemical formula is CH₃COOH, and it is the undiluted form of acetic acid. Unlike the typical vinegar that contains about 4-8% acetic acid, glacial acetic acid is approximately 99.5% pure. One of the remarkable characteristics of glacial acetic acid is its freezing point, which is a critical parameter for its use in both industrial applications and laboratory experiments.
