Isakhiwo nokwakheka
I-sodium sulfide ibamba khulu amanzi. Incibilika lula emanzini, incibilika kancani ku-ethanol, begodu ayincibiliki ku-ether. Isisombululo sayo esinamanzi sine-alkali eqinileko begodu singabanga ukutjhisa lokha nakuthintana nesikhumba nofana iinhluthu. Ngalokho-ke, i-sodium sulfide yaziwa ngokuthi yi-sulfide alkali. I-oksijini lula emoyeni begodu isebenzisana nama-esidi aqinileko ukukhupha igesi ye-hydrogen sulfide. Ingakha iinsimbi ezingancibilikiko ze-sulfide lokha nazihlanganiswa neensombululo ezihlukahlukeneko ze-heavy metal.

I-sodium sulfide inesitifiketi sesithathu se-SGS, isitifiketi sezinga lezebubulo, begodu sele iphasile isitifiketi se-ISO yamazwe ngamazwe kanye nesitifiketi sokuthobela i-REACH. Tlika lapha ukuthola isaphulelo sesaphulelo.
