Red Spiritation inogona kunge iri sodium polysulfide precipiti Kana iyo sarufa index yeSodium Polysulfide yakakwira Uye mvura (1: 6 kuita kunogona kunyorwa).
Kuzivikanwa kweiyo tsvuku-tsvuku yakadhindwa nzira nzira
Bvisa chinhu chitsvuku uye washera kakawanda nemhedziso ethanol (edza kugeza sodium sulfide solution solid. , uye woshambidza kakawanda ne ethanol.Take chidiki chidiki chekupunzika, iwe unofanirwa kushandisa zvakare, iwe zvakare unogona zvakare kutungamira acetate acetate kana kutungamira yetrate test pepa bvunzo) . Carbonate kugadzirwa (kabhoni tetrachloride Alkali Decomposition chigadzirwa).
