"Sodium phosphate" refers to a class of inorganic compounds containing sodium and phosphate ions. Sodium phosphate can exist in various forms, depending on the number of sodium (Na) and phosphate (PO4) ions in the compound.

Monosodium Phosphate (NaH2PO4):

• Also known as sodium dihydrogen phosphate.
• It is a white, crystalline powder.
• Used in the food industry as an acidity regulator, emulsifying agent, and nutrient supplement.

Disodium Phosphate (Na2HPO4):

• Also known as sodium hydrogen phosphate or secondary sodium phosphate.
• It is a white, crystalline powder.
• Used as a food additive, emulsifier, and buffering agent.

Trisodium Phosphate (Na3PO4):

• It is a white, crystalline powder.
• Used as a cleaning agent, stain remover, and degreaser. It is not typically used in the food industry due to its alkalinity.
