DESCRIPTION
Sodium Acid Pyrophosphate occurs as a white, crystalline powder or granules. It is soluble in water. The pH of a 1:100
aqueous solution is about 4. It may contain a suitable aluminum and/or calcium salt to control the rate of reaction in
leavening systems.
Function : Buffer; emulsifier; leavening agent; sequestrant.
REQUIREMENTS
Identification
A 1:20 aqueous solution gives positive tests for Sodium, Appendix IIIA.
Dissolve 100 mg of sample in 100 mL of 1.7 N nitric acid. Add 0.5 mL of this solution to 30 mL of quimociac TS.
Ayellow precipitate does not form. Heat the remaining portion of the sample solution for 10 min at 95°, and add 0.5 mL of it to 30 mL of quimociac TS. A yellow precipitate forms immediately.
Assay Not less than 93.0% and not more than 100.5% of Na2H2P2O7.
Arsenic Not more than 3 mg/kg.
Fluoride Not more than 0.005%.
Insoluble Substances Not more than 1%.
Lead Not more than 2 mg/kg.
