Sarufa oxide

Sarufa iri akaparadzirwa pasi goko, zvinotora navatanhatu nzvimbo pakati zvimwe zvinhu. It anowanikwa zvose vakasununguka mamiriro, uye vakasungwa chimiro. Metallic ehupfumi vari yo ichi makemikari maatomu akafanana. Latin zita rayo «Sarufa», runotaurwa S. The ichocho dziri siyana ions ose yeimwe ane okisijeni uye / kana rehydrogen siyana zvakawanda zvinokuvadza enzvimbo kuti makirasi asidhi munyu uye akawanda oxides imwe neimwe inogona kunzi ine sarufa oxide pamwe kuwedzera vatambi inomirira Valencia. Oxidation mamiriro nayo rinoratidza yeimwe siyana +6, +4, +2, 0, -1, -2. Anozivikanwa sarufa oxides nedzimwe oxidation inoti. The Zvinonyanyozivikanwa - payo yakasviba nesarufa trioxide. Hainyanyi kuvazivisa vari sarufa monoxide, uye yakakwirira (kunze SO3) ezasi oxides kuti maatomu akafanana izvi.

sarufa monoxide

The inorganic remubatanidzwa inonzi sarufa oxide II, SO, chitarisiko remubatanidzwa iri Hauoneki gasi. Pamusoro kuonana haisi mvura soluble, uye zvaanoita nazvo. remubatanidzwa Izvi kushoma chaizvo, kunoitika chete isingawanzowanikwi gaseous svikiro. SO morekuru thermodynamically kusagadzikana uye kuva pakutanga S2O2, (raireva disulfur gasi sarufa kana peroxide). Nokuda isingawanzowanikwi panowanikwa nesarufa monoxide kwedu mhepo uye pasi kutsiga Morekuru anonetsa kwazvo kuziva ngozi yacho fuma. Asi mune zvimwe yaiitwa yakapfupikiswa kana pfungwa chimiro oxide ichichinja peroxide, riri yakati chepfu uye kungatikanganisa. remubatanidzwa Izvi kwazvo zvinobata moto (ichi chakafanana rutivi methane) inotengwa nomoto nesarufa yakasviba - muchetura gasi. Sarufa oxide dzakaonekwa oda 2 ıO (mumwe Jupiter satellites) iri kuitika Venus uye yomuchadenga svikiro. Zvinofungirwa kuti musi ıO, ndiwo mugumisiro kuputika uye photochemical kwendangariro. Basic photochemical siyana ndeinotevera: O + S2 → S + SO uye SO2 → SO + O.

sarufa yakasviba

Sarufa oxide IV, kana nesafuri yakasviba (SO2) ndiro Hauoneki gasi unopinza kwakanaka cheYangon. Pamusangano tembiricha yakadzikira kusvika pa-10 C, ruchapinda muruoko imvura ezvinhu uye ane tembiricha yakadzikira kusvika pa-73 C solidifies. At 20 ° C muna 1 fő mvura urwa anenge 40 zvemaBhaibheri SO2.

Izvi sarufa oxide urwa mumvura siyana sulfurous acid, sezvo iri kwayo anhydride: SO2 + H2O ↔ H2SO3.

It interacts nezvigadziko uye dzinokosha oxides: 2NaOH → SO2 + Na2SO3 + H2O uye SO2 + Cao → CaSO3.

Nokuti kwese ehupfumi rwesarufa yakasviba uye oxidizing mumiririri uye kuderedza zvaanoda. Zvinonzi oxidized ne mumhepo okisijeni kuti nesarufa trioxide pamberi anowedzera: SO2 + O2 → 2SO3. With simba kuderedza nevasori akadai sehydrogen sulfide anoridza basa ane oxidant: H2S + SO2 → S + H2O.

Sarufa yakasviba inoshandiswa indasitiri zvikurukuru pagadzirwe sulfuric acid. Sarufa dioxide zvinoberekwa rinopfuta nesafuri kana simbi pyrites: 11O2 + 4FeS2 → 2Fe2O3 + 8SO2.

sarufa trioxide

Sarufa oxide VI, kana nesafuri trioxide (SO3) ane zvenguva chigadzirwa uye asina akazvimirira kukosha. In nechitarisiko chinhu Hauoneki zvokunwa. It mamota panguva tembiricha kuti 45 C uye pasi 17 C ari rinochinjwa kuva chena crystalline guru. Izvi wakakwirira oxides rwesarufa (pamwe ukuru oxidation yacho sarufa atomu + 6) inozivikanwa yokunyanyisa hygroscopicity. Nemvura anoumba sulfuric asidhi: SO3 + H2O ↔ H2SO4. Zvazvichanyungudutswa mvura, inongorira yakawanda kupisa uye, kana kwete kuwedzera zvishoma nezvishoma, uye pakarepo yakawanda ari oxide, ipapo kuputika aigona kuitika. Sarufa trioxide iri nyore soluble mune pfungwa yokushanda sulfuric asidhi kuumbika oleum. SO3 zviri anosvika 60% oleum. Nokuti ichi sarufa remubatanidzwa kunoratidzwa ehupfumi ose ane acidic oxide.

Yepamusorosoro uye ezasi oxides rwesarufa

Higher sarufa oxides vanoumba boka makemikari chete nzira SO3 + X, apo X inogona 0 kana 1. monomer oxide SO4 ane peroxo (CHAKAI) uye inozivikanwa se oxide SO3, dhigirii rwesarufa oxidation +6. Izvi sarufa oxide zvinogona kubudiswa panguva yakaderera tembiricha (pazasi 78 C) ari maitiro SO3 uye mabhomba okisijeni kana photolysis kuti SO3 iri musanganiswa pamwe ozone.

Lower sarufa oxides vanoumba boka makemikari zvinosanganisira:

• SO (sarufa oxide uye ayo dimer S2O2);
• S2O;
• SnO sarufa monoxides (vari cyclic yeimwe wakaumbwa maringi inoumbwa nesarufa maatomu, sezvamakaropafadzwa N zvingava 5 kusvika 10);
• S7O2;
• polymeric sarufa oxides.

Kufarira yepazasi zvibereko sarufa oxides. Izvi imhaka kudiwa kudzidza kugutsikana yavo pano uye extraterrestrial atmospheres.
