Sodium sulfide, gin ma ki lwongo ni inorganic compound ma ki ngeyo ni odorous alkali, odorous soda, yellow alkali, onyo sulfide alkali, tye gin ma pe ki rangi ma nen maber. En tye ki rwom me pii ma lamal ki romo gonyo i pii, ma miyo pii ma nyutu teko me alkaline. Ka ogudo del kom onyo yer twero kelo wang, pi meno ki keto nyinge ni "sulfide alkali." Ka ki keto i yamo, gin ma ki lwongo ni aqueous solution me sodium sulfide ni loko mot mot me yubu sodium thiosulfate, sodium sulfite, sodium sulfate, ki sodium polysulfide. I kin jami eni, sodium thiosulfate ki yubu oyoto, ma miyo en aye gin ma kelo oxidation. Sodium sulfide bene twero doko goro ki carbonation i yamo, ma kelo balo ki gonyo yamo ma ki lwongo ni hydrogen sulfide. Gin ma ki lwongo ni Industrial-grade sodium sulfide pol kare tye ki jami ma obale, ma miyo rangi ma calo pink, red-brown, onyo yellowish-brown. Pek pa gin ni, rwom me lyeto, ki rwom me lyeto pa gin ni twero bedo pat pat pi teko pa jami ma obale ni.

Sodium sulfide tye ki certificate pa ngat mukene ma ki lwongo ni SGS, certificate me rwom me tic, ki okato ISO international quality system certification ki REACH compliance certification.
