Sodium Metabisulfite USP NF
Na2S2O5 -- 190.11
Disulfurous acid, disodium salt.
Disodium pyrosulfite [7681-57-4]

Sodium Metabisulfite contains an amount of Na2S2O5 equivalent to not less than 65.0 percent and not more than 67.4 percent of SO2.

Identification: A solution (1 in 20) responds to the tests for Sodium 191 and for Sulfite.
Limit of chloride: Dissolve 1.0 g in 10 mL of water, filter, if necessary, through a small chloride free filter, and add 6 mL of 30 percent hydrogen peroxide. Add 1 N sodium hydroxide until the solution is slightly alkaline to phenolphthalein, dilute with water to 100 mL, and mix. Dilute 2.0 mL of this solution with water to 20 mL, and add 1 mL of nitric acid and 1 mL of silver nitrate TS. Mix, allow to stand for 5 minutes protected from direct sunlight, and compare the turbidity, if any, with that produced from a 2-mL aliquot of a control (prepared by diluting 0.71 mL of 0.020 N hydrochloric acid to 100 mL) in an equal volume of total solution containing the quantities of reagents used in the test : any turbidity produced by the test specimen does not exceed that of the control preparation (0.05%).
Iron: the limit is 0.002%.
Limit of thiosulfate: Mix 2.2 g with 10 mL of 1 N hydrochloric acid in a 50-mL beaker. Boil gently for 5 minutes, cool, and transfer to a small test tube. Any turbidity is not greater than that produced by 0.10 mL of 0.10 N sodium thiosulfate, similarly treated (0.05%).
Heavy metals: the limit is 0.002%.
