I-sodium sulfide, intfo lengaphili lephindze yatiwe ngekutsi yi-alkali leneliphunga, isoda leneliphunga, i-alkali lephuti, noma i-sulfide alkali, yimpuphu lengenambala ngendlela yayo lehlantekile. I-hygroscopic kakhulu futsi incibilika kalula emantini, ikhicita sisombululo lesinemanti lesikhombisa timphawu te alkaline letinemandla. Kutsintsana nesikhumba nobe tinwele kungabangela kushiswa, kungako ligama layo lelivamile lelitsi “sulfide alkali.” Uma sivulelekile emoyeni, lesisombululo lesinemanti se-sodium sulfide siyakhipha kancane kancane kute sakhe i-sodium thiosulfate, i-sodium sulfite, i-sodium sulfate, kanye ne-sodium polysulfide. Emkhatsini waloku, iSodium thiosulfate ikhicitwa ngesilinganiso lesisheshako, kwenta kutsi ibe ngumkhicito we oxidation loyinhloko. iSodium sulfide iphindze ibe nekuvuvuka kanye ne carbonation emoyeni, lokuholela ekuboleni kanye nekukhishwa lokuchubekako kwegesi ye hydrogen sulfide. I-sodium sulfide yesigaba setimboni ivame kuba nekungcola, kuniketa imibala lefana ne pink, lebovu-lensundvu, noma lephuti-lensundvu. I-gravity lekhetsekile, indzawo yekuncibilika, kanye nendzawo yekubila yale compound kungahluka ngenca yemtselela waletintfo letingcolile.

I-Sodium sulfide inesitifiketi se-SGS sesitsatfu, sitifiketi selizinga letimboni, futsi iphumelele sitifiketi seluhlelo lwelizinga lemhlaba wonkhe le-ISO kanye nesitifiketi sekuhambisana ne-REACH.
