Dipotassium hydrogen phosphate trihydrate

Description:
Dipotassium hydrogen phosphate trihydrate, with the CAS number 16788-57-1, is an inorganic compound that serves as a source of potassium and phosphate ions. It is typically encountered as a white crystalline solid that is hygroscopic, meaning it can absorb moisture from the air. This compound is soluble in water, forming a clear solution, and is often used in various applications, including as a buffering agent in biological and chemical processes, as well as in fertilizers due to its nutrient content. The trihydrate form indicates that each molecule of dipotassium hydrogen phosphate is associated with three water molecules, which can influence its physical properties and solubility. In terms of safety, it is generally considered to have low toxicity, but standard precautions should be taken when handling any chemical substance. Its ability to act as a pH stabilizer makes it valuable in laboratory settings and in the food industry, where it can be used as an emulsifier or stabilizer.
