Dipotassium hydrogen phosphate CAS 7758-11-4
Dibasic Potassium Phosphate contains not less than 98.0 percent and not more than 100.5 percent of K2HPO4, calculated on the dried basis.
Identification: A solution (1 in 20) responds to the tests for Potassium and for Phosphate.
pH: between 8.5 and 9.6, in a solution (1 in 20).
Loss on drying: Dry it at 105 to constant weight: it loses not more than 1.0% of its weight.
Insoluble substances: Dissolve 10 g in 100 mL of hot water, filter through a tarred filtering crucible, wash the insoluble residue with hot water, and dry at 105C for 2 hours: the weight of the residue so obtained does not exceed 20 mg (0.2%).
Carbonate: To 1 g add 3 mL of water and 2 mL of 3 N hydrochloric acid: not more than a few bubbles are evolved.
Chloride: A 1.0-g portion shows no more chloride than corresponds to 0.40 mL of 0.020 N hydrochloric acid (0.03%).
Sulfate: A 0.20-g portion shows no more sulfate than corresponds to 0.20 mL of 0.020 N sulfuric acid (0.1%).
Arsenic: 3 ppm.
Iron: the limit is 0.003%.
Sodium: A solution (1 in 10) tested on a platinum wire imparts no pronounced yellow color to a non-luminous flame.
Heavy metals: the limit is 0.001%.
Limit of fluoride: The limit is 0.001%.
Limit of monobasic or tribasic salt: Dissolve 3 g in 30 mL of water, cool to 20C, and add 3 drops of thymol blue: a blue color is produced, which is changed to yellow (with a greenish tinge) by the addition of not more than 0.4 mL of 1 N hydrochloric acid.

Function: Buffer; sequestrant; yeast food.
REQUIREMENTS
Identification: A 1:20 aqueous solution gives positive tests for Potassium and for Phosphate.
Assay: Not less than 98.0% of K2HPO4 after drying.
Arsenic: Not more than 3 mg/kg.
Fluoride: Not more than 10 mg/kg.
Insoluble Substances: Not more than 0.2%.
Lead: Not more than 2 mg/kg.
Loss on Drying: Not more than 2.0%.
