What is Sodium dihydrogen phosphate?

Sodium dihydrogen phosphate is an inorganic monobasic sodium phosphate compound with the chemical formula NaH₂PO₄. Sodium dihydrogen phosphate is a derivative composed of glycerol derivatives formed by reacting mono and diglycerides that are derived from edible sources with phosphorus pentoxide followed by neutralization with sodium carbonate. Sodium dihydrogen phosphate is a soluble form of phosphate that can be administered intravenously.

Other names – Monobasic sodium phosphate, Monosodium phosphate (MSP)

Sodium dihydrogen phosphate Structure – NaH₂PO₄

Physical Properties of Sodium dihydrogen phosphate – NaH₂PO₄

Chemical Properties of Sodium dihydrogen phosphate – NaH₂PO₄

• • • • • Sodium dihydrogen phosphate reacts with bases like sodium hydroxide resulting in the formation of sodium hydrogen phosphate and water.

NaH₂PO₄ + NaOH → Na₂HPO₄ + H₂O

• • • • • Sodium dihydrogen phosphate reacts with acid like hydrochloric acid results in the formation of phosphoric acid and sodium chloride.

NaH₂PO₄ + HCl → H₃PO₄ + NaCl

Uses of Sodium dihydrogen phosphate – NaH₂PO₄

• • • Used for water treatment were generally safe, high concentrations had the potential for interfering with human essential trace metal metabolism.
    • Phosphorus in domestic sewage may be derived from human wastes, waste food (primarily from household garbage- disposal units), and synthetic detergents.
    • Reducing the amount of phosphorus reaching the sewage treatment works by concerted public campaigns can reduce the costs of stripping gas or vapour from a foam.
