Mvula yofiira ikhoza kukhala sodium polysulfide precipitation.Sodium sulfide imatha kukhala oxidized ndi mpweya kukhala sodium polysulfide (kupanga sulfure kukhala chinthu chimodzi, kenako kutulutsa sodium polysulfide). Mlozera wa sulfure wa sodium polysulfide ukakwera, umakhala wofiyira wofiyira mu njira yamadzimadzi, ndipo umatuluka chifukwa cha njira yosasungunuka pansi pamikhalidwe yamadzi. ndi madzi (1: 6 reaction can be written) .Kuphatikiza kwa okosijeni ndi kuwonongeka kwa machitidwe kungalimbikitsenso wina ndi mzake, ndipo zochitika zina zingathenso kuchitika.

Kuzindikiritsa njira yolozera mvula yofiyira
Chotsani zinthu zofiira ndikutsuka kangapo ndi ethanol (yesani kutsuka sodium sulfide solution) kuti muwone ngati idzasungunuka. Onjezerani kaye carbon disulfide kuti muwone ngati ikutha (kufufuza sulfure yokha, ngakhale ili yachikasu) , ndikutsuka kangapo ndi ethanol.Tengani mpweya wochepa ndi kuchepetsa sulfuric acid, muwone ngati pali kuthawa kwa hydrogen sulfide (muyenera kununkhiza, mungagwiritsenso ntchito acetate wonyowa kapena kuyesa pepala loyesa nitrate) , mvula ngakhale kuchuluka kwa kutembenuka kukhala kuwala chikasu kapena yamkaka woyera turbidity, ichi ndi mankhwala sodium polysulfide (potaziyamu) chodabwitsa. kupanga carbonate (carbon tetrachloride alkali decomposition product).
