Sulfur oxide

Sulfur ne rarraba a cikin ƙasa ta ɓawon burodi, yana daukan sha shida wuri a cikin sauran abubuwa. Yana auku biyu a cikin free jihar, kuma a mamaye form. Ƙarfe Properties ne halayyar wannan sinadari. Its Latin sunan «Sulfur», denoted S. The kashi na kunshe a cikin daban-daban ions mahadi dauke da oxygen da kuma / ko hydrogen siffofin da yawa abubuwa na ga azuzuwan na acid salts da mahara oxides kowanne daga abin da za a iya kira a matsayin wata sulfur oxide da Bugu da kari haruffa wakiltar wani valence. Hadawan abu da iskar shaka jihar da shi farfado daban-daban mahadi +6, +4, +2, 0, -1, -2. Known sulfur oxides tare da daban-daban hadawan abu da iskar shaka jihohi. Mafi na kowa - da shi dioxide da sulfur trioxide. Kadan da kyau a san su sulfur monoxide, kuma mafi girma (sai dai SO3) da kuma ƙananan oxides wannan kashi.

sulfur monoxide

A inorganic fili kira sulfur oxide II, SO, bayyanar wannan fili shi ne wani colorless iskar gas. Ga lamba tare da shi ne, ba ruwa mai narkewa, da kuma reacts tare da shi. Wannan fili ne sosai rare, wanda ya auku ne kawai a cikin rare gaseous matsakaici. SO kwayoyin ne thermodynamically m, kuma an canza kama zuwa da farko S2O2, (magana disulfur gas sulfur ko peroxide). Saboda rare faru na sulfur monoxide a cikin yanayi da kuma low zaman lafiyar da kwayoyin ne da wuya zuwa cikakken gane hatsarin da abu. Amma a cikin wani more takaice ko mayar da hankali form oxide jũya a cikin peroxide, wanda shi ne gwada da mai guba da kuma lalatattu. Wannan fili shi ma sosai flammable (wannan yayi kama da alama na methane) da aka samu ta hanyar kona sulfur dioxide - mai guba gas. Sulfur oxide gano ya game 2 IO (daya daga Jupiter da tauraron dan adam) a cikin yanayi na Venus da interstellar matsakaici. An zaci cewa a IO, shi ne sakamakon aman wuta da kuma photochemical tafiyar matakai. Basic photochemical halayen su ne kamar haka: Yã + S2 → S + SO kuma SO2 → SO + O.

sulfur dioxide

Sulfur oxide IV, ko sulfur dioxide (SO2) ne a colorless iskar gas tare da kaifi wari gagarumin. A zazzabi na debe 10 C, shi da ke a cikin wani ruwa jihar da kuma a zazzabi na debe 73 C solidifies. A 20 ° C in 1 lita na ruwa dissolves kusan 40 kundin na SO2.

Wannan sulfur oxide dissolves a ruwa siffofin sulfurous acid, kamar yadda shi ne ta anhydride: SO2 + H2O ↔ H2SO3.

Yana interacts tare da kwasfansu, da asali oxides: 2NaOH → SO2 + Na2SO3 + H2O da SO2 + Cao → CaSO3.

Domin hankula Properties na sulfur dioxide da wani oxidizing wakili da kuma rage wakili. An oxidized da yanayi oxygen zuwa sulfur trioxide a gaban mai kara kuzari: SO2 + O2 → 2SO3. Tare da karfi rage jamiái kamar hydrogen sulfide, taka rawar da wani oxidant: H2S + SO2 → S + H2O.

Sulfur dioxide da ake amfani a masana'antu, yafi domin samar da sulfuric acid. Sulfur dioxide da aka samar ta hanyar kona sulfur ko kuwa baƙin ƙarfe pyrites: 11O2 + 4FeS2 → 2Fe2O3 + 8SO2.

sulfur trioxide

Sulfur oxide VI, ko sulfur trioxide (SO3) ne tsaka-tsaki samfurin kuma yana da wani m muhimmanci. A bayyanar shi ne wani colorless ruwa. Tafasa a zazzabi na 45 C da ke ƙasa 17 C an canza kama zuwa wani farin crystalline taro. Wannan mafi girma oxides na sulfur (tare da mataki na hadawan abu da iskar shaka da sulfur zarra + 6) halin matsananci hygroscopicity. Tare da ruwa shi Forms sulfuric acid: SO3 + H2O ↔ H2SO4. Narkewa a cikin ruwa, fitarda yawa zafi da kuma, idan ba ƙara hankali, da kuma nan da nan a manyan adadin da oxide, sa'an nan fashewa iya faruwa. Sulfur trioxide ne readily mai narkewa a cikin mayar da hankali sulfuric acid don ya samar oleum. SO3 abun ciki na har zuwa 60% oleum. Domin wannan sulfur fili ne halin da duk kaddarorin da wani acidic oxide.

Higher da ƙananan oxides na sulfur

Higher sulfur oxides dokoki wani rukuni na sinadaran mahadi da dabara SO3 + x, inda x iya zama 0 ko 1. The monomer oxide SO4 žunshi peroxo (OO) da kuma halin yadda oxide SO3, mataki na sulfur hadawan abu da iskar shaka +6. Wannan sulfur oxide za a iya samar a low yanayin zafi (a kasa 78 C) a dauki SO3 da atomic oxygen ko photolysis na SO3 a cakuda da lemar sararin samaniya.

Lower sulfur oxides dokoki wani rukuni na sinadaran mahadi kunshi:

• SO (sulfur oxide da dimer S2O2).
• S2O.
• SnO sulfur monoxides (ne cyclic mahadi kunshi zobba kafa ta sulfur kwayoyin halitta, a cikinsa n iya zama daga 5 zuwa 10).
• S7O2.
• polymeric sulfur oxides.

Interest a cikin ƙananan karuwa sulfur oxides. Wannan shi ne saboda bukatar ya yi nazarin su abun ciki a cikin terrestrial kuma Extraterrestrial atmospheres.
