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.

Gano hanyar ambaton hazo ja-ja
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 kuma a tsoma sulfuric acid, duba idan akwai gudun hijira na hydrogen sulfide (ya kamata ku iya jin wari, za ku iya amfani da shi. rigar gubar acetate ko gubar nitrate gwajin takarda gwajin), hazo ko babban adadin tuba zuwa haske rawaya ko milky fari turbidity, wannan shi ne samfurin na sodium polysulfide (potassium) abin mamaki.The sama gwaje-gwaje tabbatar ko sodium polysulfide (potassium). Hakanan ana iya tsara shi don tabbatar da ko akwai samar da carbonate (carbon tetrachloride alkali bazuwar samfur).
