Bismuth Citrate USP Grade Specifications
BiC6H5O7 398.08 -- CAS 813-93-4.
Bismuth Citrate contains not less than 49 percent and not more than 54 percent of bismuth (Bi).
Identification:
A: Infrared Absorption 197K : on the undried specimen.
B: When strongly heated, the salt chars, and on ignition leaves a more or less blackened residue having a yellow surface. The residue is soluble in warm nitric acid, and this solution, when dropped into a large excess of water, produces a white turbidity.
C: Dissolve 1 g in ammonia. When treated with hydrogen sulfide in excess, a black precipitate is obtained. Filter this mixture, drive off the excess hydrogen sulfide by heating, and allow to cool. To a portion of this cooled solution add an excess of calcium hydroxide and boil: a white precipitate is formed. Reserve a second portion of the cooled solution for the test for Limit of nitrate.
Arsenic: the limit is 10 microgm per g.
Limit of nitrate: To the second portion of cooled solution reserved from Identification test C, add an equal volume of sulfuric acid, mix, and allow to cool. Into the liquid, drop a crystal of ferrous sulfate, and allow to stand for 30 minutes: no brown or brownish black color appears around the crystal.
Limit of copper, lead, and silver: To pass the test; 10 microgm per g.
Limit of soluble bismuth: To pass the test.
