Beschreibung
Potassium Phosphate Dibasic 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 Potassium Phosphate Dibasic 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.Chemische Eigenschaften
White crystalline powderPhysikalische Eigenschaften
White amorphous powder; deliquesces; decomposes on heating; converts to pyrophosphate when ignited; very soluble in water, 167 g/100mL at 20°C; very soluble in alcohol; aqueous solution slightly alkaline.Verwenden
Potassium Phosphate Dibasic 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 and dipotassium monophosphate.synthetische
Dipotassium phosphate is prepared by partial neutralization of phosphoric acid with potassium hydroxide, followed by crystallization:H3PO4+ 2KOH →K2HPO4+ 2H2O.
Definition
ChEBI: A potassium salt that is the dipotassium salt of phosphoric acid.Allgemeine Beschreibung
Potassium phosphate dibasic is a useful biological buffer having a pH in the range of 8.5-9.6. Potassium phosphate is present in various forms: monobasic (KH2PO4), dibasic (KH2PO4), and tribasic (K3PO4). Potassium phosphate buffers are widely employed in equilibrium dialysis, high performance liquid chromatography (HPLC) and affinity capillary electrophoresis studies.Einzelnachweise
