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) , uye ugeze kakawanda ne ethanol.Tora zvishoma zvekunaya uye dilute sulfuric acid, ona kana pane hydrogen sulfide kutiza (iwe unofanirwa kukwanisa kunhuwa kunze, unogonawo kushandisa wet lead acetate kana lead nitrate test paper test) , kunaya kana kuwanda kweshanduko kuita yero yakajeka kana mukaka chena turbidity, ichi ndicho chigadzirwa che sodium polysulfide (potassium) chiitiko.Zviedzo zviri pamusoro zvakaratidza kana sodium polysulfide (potassium).Inogonawo kugadzirwa kuratidza kana paine carbonate production (carbon tetrachloride alkali decomposition product).
