Physical and Chemical Properties:
Sodium sulfide is the chemical compound with the formula Na2S, or more commonly its hydrate Na2S·9H2O. Both 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.
Note: The above specification is satisfy with GB105002009, also accord with European and American Standards.We can accept the Third part test.Such as BV,SGS etc.

Sodium sulfide is primarily used in the kraft process in the pulp and paper industry.
It is used in water treatment as an oxygen scavenger agent and also as a metals precipitant;
in chemical photography for toning black and white photographs;
in the textile industry as a bleaching agent, for desulfurising and as a dechlorinating agent; and in the leather trade for the sulfitisation of tanning extracts.
It is used in chemical manufacturing as a sulfonation and sulfomethylation agent.
It is used in the production of rubber chemicals, sulfur dyes and other chemical compounds.
It is used in other applications including ore flotation, oil recovery, making dyes, and detergent. It is also used during leather processing, as an unhairing agent in the liming operation.
