# Potassium dihydrogen phosphate Formula

Potassium dihydrogen phosphate formula, also named as Potassium biphosphate formula or Monopotassium Phosphate formula is discussed in this article. It is an inorganic phosphate and potassium salt. The molecular or chemical formula of Potassium dihydrogen phosphate is KH2PO4.

Monopotassium phosphate (MKP), it is also known as potassium dihydrogen phosphate (KDP), is a soluble salt of dihydrogen phosphate ion and potassium. It is a source of potassium and phosphorus. It is a potassium salt where dihydrogen phosphate is the counterion.

## Properties Of Potassium dihydrogen phosphate Formula

 Chemical formula of Potassium dihydrogen phosphate KH2PO4 Molecular weight of Potassium dihydrogen phosphate 136.086 g/mol Density of Potassium dihydrogen phosphate 2.338 g/cm3 Melting point of Potassium dihydrogen phosphate 252.6 °C Boiling point of Potassium dihydrogen phosphate 400 °C

It is widely used as a buffering agent, in fertilizers. It is mixed in ammonium phosphates and urea in fertilizers to minimize the escape of ammonia. This is done by maintaining the level of the pH relatively low.
