Mvura yakatsvuka inogona kunge iri sodium polysulfide precipitation.Sodium sulfide inowanzoita oxidized nemhepo kune sodium polysulfide (ita sarufa kuita chinhu chimwe chete, uye wozogadzira sodium polysulfide). Kana iyo sulfur index ye sodium polysulfide yakakwira, yakasviba mutsvuku mumushonga wemvura, uye inobuda nekuda kwekusagadziriswa kwekugadzirisa pasi pemamiriro ezvinhu ane anaqueous.Uyezve, carbon tetrachloride inogonawo kuora mu sodium chloride (potassium) + sodium carbonate (potassium). uye mvura (1:6 reaction inogona kunyorwa) .Kusanganiswa kwe oxidation uye kuora kwekuita kunogonawo kukurudzirana, uye mamwe maitiro anogonawo kuitika.

Kuzivikanwa kwe red-red precipitation reference method
Bvisa zvinhu zvitsvuku wogeza kakawanda neabsolute ethanol (edza kugeza sodium sulfide solution) kuti uone kuti ichanyungudika here. Wedzera imwe carbon disulfide kutanga uone kuti inogadzirisa here (kutarisa kuti sarufa chete, kunyange iri yero) , woigeza kakawanda ne ethanol.Tora mvura shoma shoma uye dilute sulfuric acid, ona kana paine hydrogen sulfide yekutiza. (iwe unofanirwa kukwanisa kunhuhwirira kunze, unogona zvakare kushandisa yakanyorova lead acetate kana lead nitrate bvunzo bepa bvunzo), kunaya kana huwandu hukuru hwekushandurwa kuita mwenje yero kana mukaka chena turbidity, ichi chigadzirwa che sodium polysulfide (potassium) the phenomenon.Zviedzo zviri pamusoro zvakaratidza kuti sodium polysulfide (potassium).Inogonawo kugadzirwa kuratidza kana pane carbonate production (carbon tetrachloride alkali decomposition product).
