Imvula ebomvu inokuba yi-sodium polysulfide precipitation.I-Sodium sulfide inokuthi ifakwe i-oxidized emoyeni kwi-sodium polysulfide (yenza isulfure ibe yinto enye, kwaye emva koko ivelise i-sodium polysulfide). Xa isalathiso sesulfure ye-sodium polysulfide iphezulu, ibomvu ebomvu kwisisombululo samanzi, kwaye ivela ngenxa yesisombululo esingenakunyibilika phantsi kweemeko ezinobumba. kunye namanzi (i-1: 6 reaction ingabhalwa) .Indibaniselwano ye-oxidation kunye ne-decomposition reactions inokukhuthazana, kunye nezinye iimpendulo ezinokuthi zenzeke.
Ukuchongwa kwendlela yereferensi yemvula ebomvu-bomvu
Susa into ebomvu kwaye uyihlambe amatyeli amaninzi nge-ethanol epheleleyo (zama ukuhlamba isisombululo se-sodium sulfide) ukuze ubone ukuba iya kunyibilika.Yongeza i-carbon disulfide kuqala ukuze ubone ukuba iyasombulula (ukukhangela isulfure yodwa, nangona iphuzi) , kwaye uhlambe amaxesha amaninzi nge-ethanol.Thatha imvula encinci kwaye uhlambulule i-asidi ye-sulfuric, ubone ukuba kukho ukuphunyuka kwe-hydrogen sulfide (kufuneka ukwazi ukuvumba, ungasebenzisa kwakhona i-acetate ye-lead emanzi okanye uvavanyo lwephepha lovavanyo lwe-nitrate) , imvula nokuba isixa esikhulu soguqulo sibe yi-turbidity ekhanyayo etyheli okanye i-milky white turbidity, le yimveliso ye-sodium polysulfide (i-potassium) isenzeko. Le mifuniselo ingentla yangqina ukuba ingaba i-sodium polysulfide (i-potassium). Isenokwenziwa ukubonisa ukuba kukho imveliso carbonate (carbon tetrachloride alkali ukubola imveliso).
