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) , ndi kusamba kangapo ndi Mowa.Tengani mpweya pang'ono ndikusungunula sulfuric acid, muwone ngati pali kuthawa kwa hydrogen sulfide. (muyenera kununkhiza, mutha kugwiritsanso ntchito chonyowa kutsogolera acetate kapena lead nitrate test paper test), mvula ngati kuchuluka kwa kutembenuka kukhala chikasu chowala kapena milky white turbidity, ichi ndi chopangidwa ndi sodium polysulfide (potaziyamu) zochitika.Zoyesera zomwe zili pamwambazi zatsimikizira ngati sodium polysulfide (potaziyamu). Ingathenso kupangidwa kuti itsimikizire ngati pali carbonate kupanga (carbon tetrachloride alkali decomposition product).
