Swihlawulekisi swa Sodium Sulfide
Fomula ya Tikhemikhali: Na2S
Ndzilo wa Molekhuli: 78.04
Xivumbeko na Vumbiwa
Sodium sulfide yina mati yotala swinene. Yi olova ku n’oka ematini, yi n’oka nyana eka ethanol naswona a yi n’oki eka ether. Nkatsakanyo wa yona wa mati wuna alkaline swinene naswona wunga vanga ku hisiwa loko wu khumbana na nhlonge kumbe misisi. Hikwalaho, sodium sulfide hi ntolovelo yi tiviwa tanihi sulfide alkali. Yi oxidize hiku olova emoyeni naswona yi endla reaction na ti acids ta matimba kuva yi humesa gasi ya hydrogen sulfide. Yinga endla ti metal sulfide precipitates letinga khulukiki loko yi endliwa na ti heavy metal salt solutions to hambana hambana.

Sodium sulfide yi na xitifikheti xa SGS xa munhu wa vunharhu, xitifikheti xa giredi ya indasitiri, naswona yi pasile xitifikheti xa sisiteme ya khwalithi ya matiko ya misava ya ISO na xitifikheti xa ku landzelela REACH. Click laha ku kuma quote leyi hungutiweke.
