Dipotassium phosphate (K 2 HPO 4) (also dipotassium hydrogen orthophosphate; potassium phosphate dibasic) is the inorganic compound with the formula K 2 HPO 4. (H 2 O) x (x = 0, 3, 6). Together with monopotassium phosphate (KH 2 PO 4. (H 2 O) x), it is often used as a fertilizer, food additive, and buffering agent. [1]
Monopotassium phosphate (MKP) (also, potassium dihydrogen phosphate, KDP, or monobasic potassium phosphate) is the inorganic compound with the formula KH 2 PO 4. Together with dipotassium phosphate (K 2 HPO 4. (H 2 O) x) it is often used as a fertilizer, food additive, and buffering agent.
Potassium phosphate is a generic term for the salts of potassium and phosphate ions including: [1] Monopotassium phosphate (KH 2 PO 4) (Molar mass approx: 136 g/mol) Dipotassium phosphate (K 2 HPO 4) (Molar mass approx: 174 g/mol) Tripotassium phosphate (K 3 PO 4) (Molar mass approx: 212.27 g/mol) As food additives, potassium phosphates have ...
The term phosphate is also used in organic chemistry for the functional groups that result when one or more of the hydrogens are replaced by bonds to other groups. These acids, together with their salts and esters , include some of the best-known compounds of phosphorus, of high importance in biochemistry , mineralogy , agriculture , pharmacy ...
Inflammation, certain cancers, and ulcers can benefit from the use of combination therapy with sodium and potassium phosphates. [1] Potassium dihydrogen phosphate, the potassium salt, is useful to human in the form of pesticides. Potassium dihydrogen phosphate is a fungicide that is used to prevent powdery mildew on many fruits. [2]
The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO 4) 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 (PO 4) −
It is a major industrial chemical, being a component of many fertilizers. The compound is an acid. Removal of all three H + ions gives the phosphate ion PO 3− 4. Removal of one or two protons gives dihydrogen phosphate ion H 2 PO − 4, and the hydrogen phosphate ion HPO 2− 4, respectively. Phosphoric acid forms esters, called organophosphates.
Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate , sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate .
