Chemical compound
Dipotassium phosphate (K2HPO4) (also dipotassium hydrogen orthophosphate; potassium phosphate dibasic) is the inorganic compound with the formula K2HPO4.(H2O)x (x = 0, 3, 6). Together with monopotassium phosphate (KH2PO4.(H2O)x), it is often used as a fertilizer, food additive, and buffering agent.[1] It is a white or colorless solid that is soluble in water.
It is produced commercially by partial neutralization of phosphoric acid with two equivalents of potassium chloride:[1]
H3PO4 + 2 KCl → K2HPO4 + 2 HCl
