Sodium Sulfide USP Grade Specifications
Na2S.9H2O -- 240.18
Sodium sulfide nonahydrate.
Disodium sulfide nonahydrate [CAS 1313-84-4].Sodium Sulfide contains not less than 98.0 percent and not more than 103.0 percent of Na2S.9H2O.
Identification: [NOTE: Conduct this test in a fume hood.] Transfer about 100 mg of Sodium Sulfide, to a suitable container, add 10 mL of 3 N hydrochloric acid, and cover the top of the container with filter paper saturated with a 0.2 M lead acetate solution: a brownish or silvery-black color forms on the paper.
Limit of iron: Dissolve about 5.0 g in 100 mL of water: the solution is clear and colorless.
Limit of sulfite and thiosulfate: Dissolve 3.0 g in 200.0 mL of filtered and degassed water. Add 100.0 mL of 0.2 N zinc sulfate, mix, and allow to stand for 30 minutes. Filter, add 1 mL of starch, and titrate 100.0 mL of the filtrate with 0.01 N iodine: not more than 3.0 mL is required.

Solution S: Dissolve 2.2 g Sodium Sulfate in carbon dioxide-free water R prepared from distilled water and dilute to 100 ml with the same solvent.
Appearance of solution: Solution S is clear and colourless.
Acidity or alkalinity: To 10 ml of solution S add 0.1 ml of bromothymol blue solution R1. Not more than 0.5 ml of 0.01 M hydrochloric acid or 0.01 M sodium hydroxide is required to change the colour of the indicator.

Sulfuric acid disodium salt, decahydrate.
Disodium sulfate decahydrate CAS 7727-73-3
Anhydrous 142.04 CAS 7757-82-6Sodium Sulfate contains ten molecules of water of hydration, or is anhydrous. It contains not less than 99.0 percent of Na2SO4, calculated on the dried basis.
Identification: A solution (1 in 20) responds to the tests for Sodium 191 and for Sulfate.
Acidity or alkalinity: To 10 mL of a solution, containing the equivalent of 1.0 g of Na2SO4-10H2O in 20 mL of water, add 1 drop of bromothymol blue TS: not more than 0.50 mL of either 0.010 N hydrochloric acid or 0.010 N sodium hydroxide is required to change the color of the solution.
Loss on drying: Dry at 105 for 4 hours: the decahydrate loses between 51.0% and 57.0% of its weight, and the anhydrous form loses not more than 0.5% of its weight.
Chloride: A portion equivalent to 1.0 g of Na2SO4-10H2O ( Sodium Sulfate Decahydrate )shows no more chloride than corresponds to 0.30 mL of 0.020 N hydrochloric acid (0.02%).
