Monosodium phosphate

It consists of sodium cations (Na+) and dihydrogen phosphate anions (H2PO−4).

The pH of such formulations is generally adjusted by mixtures of various sodium phosphates, such as this salt.

[clarification needed] It is added in animal feed, toothpaste, and evaporated milk.

Monosodium phosphate is used to detect the presence of magnesium ions in salts.

Formation of a white precipitate on the addition of ammonium chloride, ammonium hydroxide and monosodium phosphate to an aqueous or dilute HCl solution of the salt indicates presence of magnesium ions.

NFPA 704 four-colored diamond Health 0: Exposure under fire conditions would offer no hazard beyond that of ordinary combustible material. E.g. sodium chloride Flammability 0: Will not burn. E.g. water Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
