Izakhiwo ze-Sodium Sulfide
Ifomula Yamakhemikhali: Na₂S
Isisindo sama-molecule: 78.04
Isakhiwo Nokwakheka
I-Sodium sulfide i-hygroscopic kakhulu. Incibilika kalula emanzini, incibilika kancane ku-ethanol, futhi ayincibiliki ku-ether. Isixazululo sayo samanzi si-alkaline kakhulu futhi singabangela ukusha lapho sithinta isikhumba noma izinwele. Ngakho-ke, i-sodium sulfide yaziwa kakhulu ngokuthi i-sulfide alkali. I-oxidizes kalula emoyeni futhi isabela nama-asidi aqinile ukuze ikhiphe igesi ye-hydrogen sulfide. Ingakha ama-precipitate e-metal sulfide angancibiliki lapho isabela ngezixazululo ezahlukene zikasawoti wensimbi esindayo.

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. Chofoza lapha ukuze uthole isilinganiso esinesaphulelo.
