Ca2P2O7 Formula wt 254.10
INS: 450(vi) CAS: [7790-76-3]

Calcium Pyrophosphate occurs as a fine, white powder. It is insoluble in water, but is soluble in dilute hydrochloric and nitric acids.
Function: Buffer; neutralizing agent; nutrient.

A. Dissolve about 100 mg of sample by warming it with a mixture of 5 mL of 2.7 hydrochloric acid and 5 mL of water; while shaking, add 2.5 mL of 6 ammonium hydroxide, dropwise, and then add 5 mL of ammonium oxalate. A white precipitate forms.
B. Dissolve 100 mg of sample in 100 mL of 1.7 nitric acid. Add 0.5 mL of this solution to 30 mL of quimociac.A yellow precipitate does not form. Heat the remaining portion of the sample solution for 10 min at 95C, and then add 0.5 mL of the solution to 30 mL of quimociac. A yellow precipitate forms immediately.
Assay: Not less than 96.0% of Ca2P2O7.
Arsenic: Not more than 3 mg/kg.
Fluoride: Not more than 0.005%.
Lead: Not more than 2 mg/kg.
Loss on Ignition: Not more than 1%.
