Munzvimbo dzemurabhoritari, kungwarira kwakawanda kunodiwa pakubata sodium sulfide. Usati washandisa, magirazi ekuchengetedza nemagirovhosi erabha zvinofanirwa kupfekwa, uye mashandiro acho anofanirwa kuitwa mukati mefume hood. Kana bhodhoro re reagent ravhurwa, rinofanira kuvharwa pakarepo mubhegi repurasitiki kudzivirira kupinza kwehunyoro kubva mumhepo, izvo zvinozoshandura kuita paste. Kana bhodhoro rikadonhedzwa netsaona, usasukurudze nemvura! Kutanga, vhara mvura yadururwa nejecha rakaoma kana ivhu, wozoiunganidza uchishandisa foshoro yepurasitiki mumudziyo wemarara wakatsaurirwa.

Kushanda pamwe chete nesu hakuna kunyanya kushushikana, kupa zvitupa zvekuongorora zveCOA zvemahara uye mapepa ekuchengetedza eMSDS, pamwe nekutsigira bvunzo dzevamwe. Shamwari dzine zvinodiwa dzinogamuchirwa kutibata chero nguva nekudzvanya pano!
