Potassium Dihydrogen Phosphate Formula

Potassium dihydrogen phosphate Formula

Potassium Dihydrogen Phosphate Formula is a potassium salt containing the counterion dihydrogen phosphate(1-). It functions as a fertiliser. It is an inorganic phosphate and a potassium salt. The soluble salt of potassium and the dihydrogen phosphate ion is known as monopotassium phosphate (MKP), potassium dihydrogen phosphate (KDP), or monobasic potassium phosphate (KH2PO4). It is a phosphorus and potassium source, and also a buffering agent. By maintaining a low pH, it can be utilised in fertiliser blends to lessen ammonia escape.

Potassium dihydrogen phosphate Formula Structure

There are numerous polymorphs of Potassium Dihydrogen Phosphate Formula. It creates tetragonal-symmetric paraelectric crystals at ambient temperature. It changes into an orthorhombic symmetry ferroelectric phase at a temperature of about -150 °C (-238 °F), and when hydrogen is substituted with deuterium, the transition temperature rises to around -50 °C (-58 °F).  When heated to 190 °C (374 °F), it transforms into a monoclinic form. At 400 °C (752 °F), MKP decomposes into potassium metaphosphate, KPO 3, via the loss of water.

Properties Of Potassium dihydrogen phosphate

Potassium dihydrogen phosphate are crystals that have no smell or colour and look like white granular or crystalline powder. The melting point is 253 °C. It is completely water-soluble. It is insoluble in ethanol. Monopotassium phosphate is so much beyond its Curie point when it is at room temperature that it produces piezoelectric effects, where the emf is proportional to the distorting force. Almost no hysteresis exists in it.

Use Of Potassium dihydrogen phosphate

Potassium dihydrogen phosphate is used in buffers, nutrient solutions, yeast foods, special liquid fertilisers, sonar systems, and other electronic applications. It is used in pharmaceutical manufacturing, buffering urine, paper processing, baking powder, and food. It is also used in wastewater treatment, as a nonlinear optical material for lasers, and as a dietary supplement in food.
