What Is Dipotassium Phosphate

It is completely normal to wonder about what is dipotassium phosphate.  You might have heard or read this somewhere or in school. The words seem to be big but don’t worry I will make it easy for you. Plus I will tell you the properties, uses, and benefits of the same. You will also get to know much more about this unique substance. So let’s not waste time and begin gaining knowledge about what is dipotassium phosphate.

What Is Dipotassium Phosphate?

Dipotassium phosphate is a man-made chemical substance that belongs to the class of inorganic compounds. It is a colorless white water-soluble salt with a great source of potassium and phosphorous. Another name of dipotassium phosphate is “dipotassium hydrogen phosphate”. It is derived from the elements of potassium, sodium, and phosphorous. They play an important role in the production of high-energy molecules named adenosine triphosphate in your body. They are found in dry as well as the liquid form which is edible. You can continue reading to know what is the dipotassium hydrogen phosphate formula.

What Is Chemical Formula For Dipotassium Phosphate?

The chemical formula for Dipotassium phosphate is K2HPO4.


K = Potassium
