Phosphates: Salts of Phosphoric Acid
The salts of phosphoric acid are termed as Phosphates. The important phosphates of Phosphoric Acid are:
- Calcium phosphate
- Ammonium phosphate
- Sodium phosphate
Calcium Phosphate
Calcium phosphate also known as superphosphate is formed by the reaction of phosphate rock with sulphuric acid. It is mainly used as a fertilizer. The chemical reaction involved in the formation of calcium phosphate is:
Ca3(PO4)2 + H2SO4→Ca(H2PO4)2 + 2CaSO4
Ammonium Phosphate
Ammonium phosphate is formed by combining phosphoric acid with anhydrous ammonia in adequate quantity. Diammonium hydrogen phosphate and monoammonium dihydrogen phosphate are types of ammonium phosphate which are used as fertilizers to increase the amount of nitrogen and phosphorus in crops.
Sodium Phosphate
Sodium phosphates are solid crystals that are formed by the reaction of phosphoric acid with concentrated solution of sodium hydroxide. Disodium hydrogen phosphate, Disodium pyrophosphate, Trisodium phosphate, and Monosodium dihydrogen phosphate are some examples of sodium phosphate.
Phosphoric Acid
Phosphoric acid is a colorless, odorless, inorganic compound. It is mainly found as an aqueous solution with a concentration of about 85%. It is represented by the chemical formula H3PO4. It is extensively used in distinct fields. Its applications include its usage in manufacturing fertilizers, various pharmaceutical products, skin care products, and much more.
In this article, we will do an in-depth study of Phosphoric acids, their properties, their usage, and others in detail.
