I-Sodium sulfide, ikhompawundi engaphiliyo ekwaziwa ngokuba yi-omerous alkali, i-omerous soda, i-yellow alkali, okanye i-sulfide alkali, yi-crystalline powder engenambala kwimo yayo ecocekileyo. I-hygroscopic kakhulu kwaye inyibilika lula emanzini, ivelisa isisombululo samanzi esibonisa iimpawu ze-alkaline ezinamandla. Ukudibana nolusu okanye iinwele kunokubangela ukutsha, yiyo loo nto igama layo eliqhelekileyo lisithi "sulfide alkali." Xa ivezwa emoyeni, isisombululo samanzi se-sodium sulfide siyanyibilika kancinci kancinci ukuze senze i-sodium thiosulfate, i-sodium sulfite, i-sodium sulfate, kunye ne-sodium polysulfide. Phakathi kwezi, i-sodium thiosulfate iveliswa ngesantya esikhawulezayo, nto leyo eyenza ukuba ibe yimveliso ephambili ye-oxidation. I-sodium sulfide ikwanokuthambekela ekuqhekekeni nasekukhutshweni kwe-carbonation emoyeni, nto leyo ekhokelela ekuboleni nasekukhutshweni okuqhubekayo kwegesi ye-hydrogen sulfide. I-sodium sulfide yodidi lweshishini idla ngokuqulatha ukungcola, okunika imibala efana nepinki, ebomvu-mdaka, okanye tyheli-mdaka. Ubunzima obuthile, indawo yokunyibilika, kunye nendawo yokubila yekhompawundi inokwahluka ngenxa yempembelelo yale mingcipheko.

I-Sodium sulfide inesatifikethi se-SGS somntu wesithathu, isatifikethi sezinga lemizi-mveliso, kwaye iphumelele isatifikethi se-ISO samazwe ngamazwe somgangatho kunye nesatifikethi sokuthobela imithetho ye-REACH.
