Sodium Sulfide
Pure USP FCC Food Grade
Sodium Sulfide

Sodium sulfide Na2S, or more commonly its hydrate Na2S·9H2O are colorless water-soluble salts that give strongly alkaline solutions. When exposed to moist air, Na2S and its hydrates emit hydrogen sulfide, which smells like rotten eggs. Some commercial samples are specified as Na2S·xH2O, where a weight percentage of Na2S is specified. Commonly available grades have around 60% Na2S by weight, which means that x is around 3. Such technical grades of sodium sulfide have a yellow appearance owing to the presence of polysulfides. These grades of sodium sulfide are marketed as 'sodium sulfide flakes'. Although the solid is yellow, solutions of it are colorless.

Sodium Sulfide USP Grade
Na2S.9H2O 240.18
Sodium sulfide nonahydrate.
Disodium sulfide nonahydrate [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.
Assay: Transfer about 275 mg of Sodium Sulfide, accurately weighed, to a 250-mL beaker, dissolve in 30 mL of filtered and degassed water, and mix. Add 50.0 mL of 0.1 N iodine while mixing, add 2 mL of hydrochloric acid, and allow to stand for 15 minutes in a dark place. Titrate with 0.1 N sodium thiosulfate VS to a pale yellow color. Add 5 mL of starch and titrate with 0.1 N sodium thiosulfate to a clear endpoint. Perform a blank determination, and make any necessary correction. Each mL of 0.1 N sodium thiosulfate is equivalent to 12.01 mg of Na2S.9H2O.

5. Fire Fighting Measures

Flammability of the Product: Non-flammable.
Products of Combustion: Sulphur oxides, Sodium oxides, fumes.
Fire: Sodium Sulfide Nonahydrate is not considered to be a fire hazard.
Fire Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Use water to cool fire-exposed containers.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures or when moistened under fire conditions, it may produce toxic or irritating fumes. On decomposition it may emit hydrogen sulfide. Containers may explode on heating

6. Accidental Release Measures

Small Spill: Avoid dust formation. Avoid breathing dust. Ensure adequate ventilation. Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.
Large Spill: Sodium Sulfide Nonahydrate is a corrosive solid. Avoid touching the spilled material. Do not let the product enter drains. Use a shovel to put the material into a convenient waste disposal container. Do not contaminate the environment.

7. Handling and Storage

Do not ingest. Do not breathe dust. Wear suitable protective clothing. In case of insufficient ventilation, wear suitable respiratory equipment.
Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Wash hands thoroughly after handling. Provide appropriate exhaust ventilation at places where dust is formed. If you feel unwell, seek medical attention.
Keep Sodium Sulfide Nonahydrate in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Keep away from incompatibles such as oxidizing agents, metals, acids.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits: Not established for the product. However, if Hydrogen sulfide is released in handling and use, then observe its limits.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
