Sodium sulfide, ihe mejupụtara inorganic nke a makwaara dịka alkali na-esi ísì ụtọ, soda na-esi ísì ụtọ, alkali odo odo, ma ọ bụ alkali sulfide, bụ ntụ ntụ kristal na-enweghị agba n'ụdị ya dị ọcha. Ọ na-adị oke hygroscopic ma na-agbaze ngwa ngwa na mmiri, na-enye mmiri mmiri nke na-egosipụta ike alkaline siri ike. Mmetụ aka na akpụkpọ ahụ ma ọ bụ ntutu nwere ike ibute ọkụ, ya mere aha a na-akpọkarị ya "sulfide alkali." Mgbe a na-ekpughe ya na ikuku, mmiri mmiri nke sodium sulfide na-agbaze nwayọ nwayọ iji mepụta sodium thiosulfate, sodium sulfite, sodium sulfate, na sodium polysulfide. N'ime ndị a, a na-emepụta sodium thiosulfate n'ọsọ ọsọ, na-eme ka ọ bụrụ ngwaahịa oxidation bụ isi. Sodium sulfide na-enwekarị ike ịla n'iyi na carbonation n'ikuku, na-eduga na ire ere na mwepụta hydrogen sulfide na-aga n'ihu. Sodium sulfide nke ụlọ ọrụ mmepụta ihe na-enwekarị ihe ndị na-adịghị ọcha, na-enye agba dị ka pink, ọbara ọbara-agba aja aja, ma ọ bụ aja aja-acha odo odo. Ike ndọda kpọmkwem, ebe agbaze, na ebe esi mmiri nke ihe mejupụtara ahụ nwere ike ịdị iche n'ihi mmetụta nke ihe ndị a na-adịghị mma.

Sodium sulfide nwere asambodo nke SGS nke ndị ọzọ, asambodo ọkwa ụlọ ọrụ mmepụta ihe, ma agafeela asambodo sistemụ mma mba ụwa ISO na asambodo nrubeisi REACH.
