Dibasic Sodium Phosphate Dibasic
Di-Sodium Phosphate or Disodium Phosphate (Na2HPO4, DSP) or disodium phosphate or dibasic sodium phosphate or sodium phosphate dibasic is a sodium salt of phosphoric acid. It is a white powder that is highly hygroscopic and water soluble. Disodium phosphate is therefore used commercially as an anti-caking additive in powdered products. It is also known as Di sodium hydrogen orthophosphate, sodium hydrogen phosphate or sodium phosphate dibasic. Sodium Phosphate Dibasic is commercially available in both the hydrated and anhydrous forms.
Other uses
Disodium phosphate DSP or Sodium Phosphate Dibasic can be used in cream of
wheat to quicken cook time.
Disodium phosphate DSP or Sodium Phosphate Dibasic is used in conjunction
with TSP
in many steam boiler applications. Sodium Phosphate Dibasic supplies the inventory of free phosphates
to retard calcium scale formation.

Dibasic Sodium Phosphate is dried or contains one, two, seven, or twelve molecules of water of hydration. It contains not less than 98.0 percent and not more than 100.5 percent of Na2HPO4, calculated on the dried basis.
Identification A solution (the equivalent of 1 part of Na2HPO4 in 30)
responds to the tests for Sodium and for Phosphate.
Loss on
drying Dry it at 130 to constant weight: the dried form loses not more than
5.0% of its weight, the monohydrate loses between 10.3% and 12.0% of its weight,
the dehydrate loses between 18.5% and 21.5% of its weight, the heptahydrate
loses between 43.0% and 50.0% of its weight, and the dodecahydrate loses between
55.0% and 64.0% of its weight.
Insoluble substances Dissolve the equivalent of 5.0 g of Na2HPO4 in 100 mL
of hot water, filter through a tarred filtering crucible, wash the insoluble
residue with hot water, and dry at 105 for 2 hours: the weight of the residue so
obtained does not exceed 20 mg (0.4%).
Chloride A portion equivalent to 0.5 g of Na2HPO4 shows no more chloride
than corresponds to 0.42 mL of 0.020 N hydrochloric acid (0.06%).
Sulfate A portion equivalent to 0.1 g of Na2HPO4 shows no more sulfate than
corresponds to 0.2 mL of 0.020 N sulfuric acid (0.2%).

be anhydrous or contain two molecules of water of hydration. The anhydrous form
is hygroscopic. Both forms are freely soluble in water and insoluble in alcohol.
Function: Emulsifier; texturizer; buffer; nutrient.
REQUIREMENTS
Identification: A 1:20 aqueous solution gives positive tests for
Phosphate
and for Sodium.
Assay: Not less than 98.0% of Na2HPO4 after drying.
Arsenic: Not more than 3 mg/kg.
Fluoride: Not more than 0.005%.
Insoluble Substances: Not more than 0.2%.
Lead: Not more than 4 mg/kg.
Loss on
Drying Anhydrous: Not more than 5.0%; Dihydrate: Between 18.0%
and 22.0%.
