Ruwan jan ruwa na iya zama hazo sodium polysulfide.Sodium sulfide zai iya zama oxidized ta iska zuwa sodium polysulfide (yi sulfur ya zama abu ɗaya, sannan ya samar da sodium polysulfide). Lokacin da sulfur index na sodium polysulfide yana da girma, yana da duhu ja a cikin bayani mai ruwa, kuma yana fitowa saboda maganin da ba zai iya narkewa ba a ƙarƙashin yanayin anaqueous. Bugu da ƙari, carbon tetrachloride zai iya rushe cikin sodium chloride (potassium) + sodium carbonate (potassium). da ruwa (1: 6 amsa za a iya rubuta) .Haɗin haɗin oxidation da lalata halayen na iya inganta juna, kuma wasu halayen na iya faruwa.

Cire jan abu a wanke shi sau da yawa tare da cikakken ethanol (kokarin wanke maganin sodium sulfide) don ganin ko zai narke.A ƙara ɗan carbon disulfide don ganin ko ya warware (don bincika sulfur kadai, ko da yake rawaya ne). , da kuma wanke shi sau da yawa tare da ethanol. Ɗauki ƙananan hazo da kuma tsarma sulfuric acid, duba idan akwai gudun hijirar hydrogen sulfide (ya kamata ku iya jin wari, kuna iya amfani da rigar gubar acetate ko gubar nitrate gwajin takarda) , Hazo ko babban adadin juyawa zuwa launin rawaya mai haske ko launin ruwan madara, wannan shine samfurin sodium polysulfide (potassium) abin mamaki. Gwaje-gwajen da ke sama sun tabbatar ko sodium polysulfide (potassium) . Hakanan za'a iya tsara shi don tabbatar da ko akwai samar da carbonate (carbon tetrachloride alkali bazuwar samfurin).
