Description

Dipotassium phosphate (K2HPO4) (also dipotassium hydrogen orthophosphatepotassium phosphate dibasic) is a highly water-soluble salt which is often used as a fertilizer, food additive and buffering agent. It is a common source of phosphorus and potassium.A dipotassium phosphate solution is formed by the stoichiometric reaction of phosphoric acid with two equivalents of potassium hydroxide:H3PO4 + 2 KOH → K2HPO4 + 2 H₂O

Application

Dipotassium hydrogenphosphate serves multiple functions across various industries. Primarily, it works as a stabilizing salt, buffer, and sequestrant, thanks to its mildly alkaline nature with a pH of 9. Its high water solubility (170 g/100 ml at 25°C) makes it effective in improving protein solubility and maintaining pH stability. This compound is widely used in the food industry, acting as a buffer in products like coffee whiteners to prevent feathering and as an emulsifier in certain cheeses. In industrial applications, it is a crucial component in fertilizers, providing essential phosphorus and potassium. In the medical field, it functions as a diuretic or laxative, and in laboratories, it's utilized for preparing buffer solutions and agar plates for bacterial culture. Additionally, dipotassium hydrogenphosphate finds use as a corrosion inhibitor in antifreeze, a nutrient in antibiotic culture medium, and an additive to enhance food quality by improving metal ion complexes, pH, and water retention. It is also employed in water treatment and as a feed phosphorus supplement.
