I-Sodium sulfide, inhlanganisela engaphili eyaziwa nangokuthi i-alkali enuka kamnandi, i-soda enuka kamnandi, i-alkali ephuzi, noma i-alkali ye-sulfide, iyimpuphu ekristalu engenambala ngesimo sayo esimsulwa. I-hygroscopic kakhulu futhi incibilika kalula emanzini, ikhipha isisombululo samanzi esibonisa izakhiwo ze-alkaline ezinamandla. Ukuthintana nesikhumba noma izinwele kungabangela ukusha, yingakho igama layo elivamile libizwa ngokuthi “i-sulfide alkali.” Uma ivezwa emoyeni, isixazululo samanzi se-sodium sulfide siyancibilika kancane kancane ukuze sakhe i-sodium thiosulfate, i-sodium sulfite, i-sodium sulfate, kanye ne-sodium polysulfide. Phakathi kwalokhu, i-sodium thiosulfate ikhiqizwa ngesivinini esisheshayo, okwenza kube umkhiqizo oyinhloko we-oxidation. I-Sodium sulfide nayo ithambekele ekuqhekekeni nasekufakweni kwe-carbon emoyeni, okuholela ekuboleni nasekukhishweni okuqhubekayo kwegesi ye-hydrogen sulfide. I-sodium sulfide yezinga lezimboni ivame ukuqukethe ukungcola, okunikeza imibala efana ne-pink, ebomvu-nsundu, noma onsundu-ophuzi. Ubukhulu obuthile bamandla adonsela phansi, iphuzu lokuncibilika, kanye nephuzu lokubila lenhlanganisela kungahluka ngenxa yethonya lalokhu kungcola.

I-Sodium sulfide inesitifiketi se-SGS esivela eceleni, isitifiketi sezinga lezimboni, futhi iphumelele isitifiketi se-ISO international quality system kanye nesitifiketi sokuthobela imithetho ye-REACH.
