Uses
Dipotassium Phosphate is the dipotassium salt of phosphoric acid which functions as a stabilizing salt, buffer, and sequestrant. It is mildly alkaline with a ph of 9 and is soluble in water with a solubility of 170 g/100 ml of water at 25°c. It improves the colloidal solubility of proteins. It acts as a buffer against variation in ph. For example, it is used in coffee whiteners as a buffer against ph variation in hot coffee and to prevent feathering. It also functions as an emulsifier in specified cheeses and as a buffering agent for processed foods. It is also termed dipotassium monohydrogen orthophosphate, potassium phosphate dibasic, and dipotassium monophosphate.
Uses
dipotassium phosphate is used as a buffering agent to control the degree of acidity in solutions.

Description
Dipotassium phosphate (K2HPO4) is a common source of phosphorus and potassium, which is often used as a fertilizer. It is also widely applied in the food industry, such as food additive and electrolyte replenisher for workout supplement. Another usage of dipotassium phosphate is as a medicine, who serves as a diuretic or laxative. Besides, it is employed in the production of imitation dairy creamers to prevent coagulation and used in certain powders to prepare beverages. In addition, it is commonly seen in chemical laboratories for producing buffer solutions and trypticase soy agar which is used to make agar plates for culturing bacteria.
