Potassium Dihydrogen Phosphate, Formula, Chemical Properties, Preparation, Uses

Potassium Dihydrogen Phosphate

Potassium dihydrogen phosphate is an inorganic compound that has the combination of potassium and dihydrogen ion. It is a well buffering agent. It is mainly used for the manufacturing the fertilizers. These potassium is highly effective chemical compound and we can easily enumerate the properties of the potassium dihydrogen phosphate. It reacts with the other chemical compounds and some are no chemical reactions.  The systematic IUPAC name is known as potassium dihydrogen phosphate . The chemical or molecular formula of potassium dihydrogen phosphate is KH2PO4. It is also known as monobasic potassium phosphate.

Structural Formula

This is the structural formula of the potassium dihydrogen phosphate:

Potassium Dihydrogen Phosphate

Chemical Formula

Chemical formula of the Potassium dihydrogen phosphate is KH2PO4.

Preparation Method

When the potassium is reacted with the phosphate and it gives the formation of the potassium dihydrogen phosphate. It could be the loss of water at 400C, it will form the metaphosphate. It gives the piezoelectric effect when the monopotassium phosphate is above the ordinary temperatures. At that point the distorting force is directly proportional to the emf.
