Sodium sulfide, ib qho inorganic compound tseem hu ua odorous alkali, odorous soda, yellow alkali, lossis sulfide alkali, yog ib qho hmoov crystalline tsis muaj xim hauv nws daim ntawv ntshiab. Nws yog hygroscopic heev thiab yooj yim soluble hauv dej, ua rau cov kua dej uas muaj cov khoom alkaline muaj zog. Kev sib cuag nrog daim tawv nqaij lossis plaub hau tuaj yeem ua rau kub hnyiab, yog li nws lub npe hu ua "sulfide alkali." Thaum raug rau huab cua, cov kua dej ntawm sodium sulfide maj mam oxidizes los ua sodium thiosulfate, sodium sulfite, sodium sulfate, thiab sodium polysulfide. Ntawm cov no, sodium thiosulfate yog tsim ntawm tus nqi sai dua, ua rau nws yog cov khoom oxidation thawj zaug. Sodium sulfide kuj tseem yooj yim rau deliquescence thiab carbonation hauv huab cua, ua rau decomposition thiab txuas ntxiv tso tawm cov roj hydrogen sulfide. Qib kev lag luam sodium sulfide feem ntau muaj cov khoom tsis huv, muab cov xim xws li liab dawb, xim av liab, lossis xim av daj. Lub zog tshwj xeeb, melting point, thiab boiling point ntawm cov tshuaj yuav txawv vim yog kev cuam tshuam ntawm cov khoom tsis huv no.

Sodium sulfide muaj daim ntawv pov thawj thib peb ntawm SGS, daim ntawv pov thawj qib kev lag luam, thiab tau dhau daim ntawv pov thawj thoob ntiaj teb ISO thiab daim ntawv pov thawj ua raws li REACH.
