Dihydrogenfosforečnan draselný

Potassium phosphate is a reagent with high buffering capacity. It occurs in several forms: monobasic, dibasic, and tribasic (K3PO4). Most pH neutral potassium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH.


Potassium Phosphate Monobasic is used as a component for a wide variety of media used in the culture of microorganisms, as a component in phosphate buffered saline (PBS). In addition to helping maintain pH, it supplies essential phosphate.


Soluble in water (0,5 g in 10 ml water), insoluble to slightly soluble in ethanol; insoluble in alcohol.
