Sodium hydrosulfide is a white or colorless hygroscopic crystals readily soluble in water.
Forms crystalline hydrates. It is a weakly hydrolyzable salt - an acidic salt of sodium and hydrogen sulfide.
It melts without decomposition; in the molten state, sodium hydrosulfide has a black color.
A typical reducing agent, oxidized by atmospheric oxygen.
Synonyms and international names
Sodium sulfohydrate, sodium sulphide acid, sodium bisulfide, Sodium Hydrosulfide (NaHS)
Application
used in the leather industry as a component of the composition for removing the outer layer of skins;
used as a raw material in the chemical industry (for the production of ethyl mercaptan, butyphos, dyes), in the textile industry
Packaging
Sodium hydrosulfide is packed in 25 kg polypropylene bags.
Storage
Sodium hydrosulfide is stored in closed dry warehouses.
Isolation of hydrogen sulfide from sodium hydrosulfide solution is possible, therefore, storage of sodium hydrosulfide together with liquids, especially acids, is unacceptable.
The guaranteed shelf life of the product is 1 year from the date of manufacture.
