Potassium hydrogen phosphate, also known as dipotassium phosphate, is an inorganic white odorless crystalline salt that is highly soluble in water. It is prepared by the partial neutralisation of phosphoric acid with potassium hydroxide or potassium carbonate.
Chemical Formula: K2HPO4
Molecular Formula: HK2O4P
Potassium is an alkali metal that belongs to group 1 of the periodic table. It is the lightest and driest soft metal. It is a silvery white metallic element with an atomic weight of 19 and has a tasteless, odorless, colorless, and flammable appearance.
It is an essential cation for cells and plays an important role in maintaining the normal pH of the cell. It is also the main source of phosphorus inside cells and plays an important role in protein synthesis.
In addition to its use in the laboratory, potassium phosphate is used as a buffering agent, a fertilizer, and a radioprotective agent. It is also used as a dietary supplement in food, dairy products, and vitamin supplements.
It is a very useful substance for reducing the coagulation of food and is widely used in macaroni and pasta, meat, milk evaporated, canned sauces, chocolates, and non-dairy creamers. It also acts as a preservative and is useful in inhibiting the growth of bacteria. It is a common ingredient in paper processing, yeast feed, and as a chemical reagent for Pharmaceuticals. It is a strong corrosion inhibitor and possesses a high pH value. It is also a source of electrolyte for athletes, assisting in their recovery from exercise and muscle pain.
