DEFINITION
Calcium Citrate contains four molecules of water of hydration. When dried at 150C to constant weight, it contains NLT 97.5% and NMT 100.5% of Ca3(C6H5O7)2.

IDENTIFICATION
A.
Analysis: Dissolve 0.5 g in a mixture of 10 mL of water and 2.5 mL of 2 N nitric acid. Add 1 mL of mercuric sulfate TS, heat to boiling, and add 1 mL of potassium permanganate.
Acceptance criteria: A white precipitate is formed.

Sample: 0.5 g of Calcium Citrate
Analysis: Ignite completely the Sample at as low a temperature as possible, cool, and dissolve the residue in dilute glacial acetic acid (1:10). Filter, and add 10 mL of ammonium oxalate to the filtrate.
Acceptance criteria: A voluminous white precipitate that is soluble in hydrochloric acid is formed.

ASSAY
Procedure
Sample solution: Dissolve 350 mg of Calcium Citrate, previously dried at 150C to constant weight, in 12 mL of 0.5 M hydrochloric acid, and dilute with water to about 100 mL.
Analysis: While stirring the Sample solution, add 30 mL of 0.05 M edetate disodium from a 50-mL burette. Add 15 mL of 1 N sodium hydroxide and 300 mg of hydroxy naphthol blue and continue the titration to a blue endpoint. Each mL of 0.05 M edetate disodium is equivalent to 8.307 mg of calcium citrate (Ca3&(C6H5O7)2).
Acceptance criteria: 97.5% to 100.5% on the dried basis
