  • In laboratories, concentrated glacial acetic acid is an indispensable reagent. It is often utilized in the synthesis of various organic compounds and serves as a solvent for reactions where a strong acid is required. Furthermore, it is used in titrations to determine the concentration of bases or other alkaline substances. Its role as a dehydrating agent in organic synthesis is also noteworthy, particularly in the production of anhydrides and acetates.

  • Potassium sorbate, also known as E202, is a salt of sorbic acid which is naturally found in some fruits (originally found in the mountain ash tree). As a potassium salt, potassium sorbate is used as a food preservative and is now produced synthetically. This preservative breaks down into water and carbon dioxide in your body. At room temperature, it looks like a white crystalline powder, but the mixture will quickly dissolve in water, which will revert it back to sorbic acid as the potassium dissolves. Some forms of potassium sorbate appear as a yellowish powder which can be dissolved in propylene glycol, ethanol or water to create a preservative with a variety of pH levels. This chemical can easily be produced and is quite inexpensive, making it an ideal choice for many industrial applications as well. While the material is generally considered safe for contact and consumption, it can be harmful if it is used excessively.

  • Phosphoric acid is an inorganic acid characterized by its ability to dissolve metals and its moderate corrosiveness. It appears as a colorless, odorless, and viscous liquid, which can also be found in crystalline form. The primary industrial applications of phosphoric acid include the production of fertilizers, food additives, and dental products. It serves as a source of phosphorus for plants, helping them grow, especially in fertilizer formulations.
