Sodium SulfiteSodium Sulfite USP NF Grade Specifications
Na2SO3 -- 126.0 CAS 7757-83-7Contains not less than 95.0 percent and not more than 100.5 percent of Na2SO3
Identification:
A: Dissolve 5 g of in 100 mL of water. [NOTE—Reserve portions of the solution so obtained for use in Identification test B and in the test for Color and clarity of solution.] Add a drop of phenolphthalein TS: a pink color is produced.
B: To 5 mL of the solution from Identification test A, add 0.5 mL of iodine TS: the solution is colorless, and it meets the requirements of the barium chloride test for Sulfate.
C: It meets the requirements of the pyroantimonate precipitate test for Sodium.Color and clarity of solution: Examine the solution prepared for Identification test A: the solution is clear and colorless.
Heavy metals: 10 3g per g, the Test Preparation being prepared as follows. To 8.0 g of Sodium Sulfite add 25 mL of water. Shake until mostly dissolved, and slowly and carefully add 15 mL of hydrochloric acid. Heat to boiling. Cool, and dilute with water to 100.0 mL. Use a 25-mL portion.
Limit of iron: not more.
Limit of selenium: not more than 10 3g per g is found.
Limit of thiosulfates: not more than 25 µg per g is found.
