Sulphur oxide

Isalfure isasazwa ngamandlakazi komhlaba, kuthatha indawo elinesithandathu phakathi kwezinye izinto. Senzeka zombini ngokwaseburhulumenteni simahla, yaye ngendlela yento. Iipropati ebuntsimbi aba uphawu lwesi sakhi chemical. igama layo Latin «Isalfure», zibonakaliswe S. The isiqalelo ifakiwe ion ezahlukeneyo iikhompawundi eziqulathe iifom ioksijini kunye / okanye hydrogen izinto ezininzi ukubayinxalenye iindidi neetyuwa acid kunye oxides ezininzi nganye ezinokuthi ngokubizwa ngokuba oxide sulphur kongezwe abalinganiswa emele Valence. Igcwala karhulumente apho kwimiboniso iikhompawundi ezahlukeneyo +6, +4,-phinde ngo 2, 0, -1, -2. oxides sulphur eyaziwa kunye namachibi ezahlukeneyo States. Eyona eqhelekileyo - it dioxide kunye nesalfure trioxide. Ngaphantsi eyaziwayo kakuhle sulphur monoxide, kwaye ngaphezulu (ngaphandle SO3) kunye oxides asezantsi lwesi sakhi.

sulphur monoxide

Umchiza ezingaphiliyo ekuthiwa sulphur oxide II, SO, imbonakalo le umchiza yigesi enemibala. Phezu udibane nazo akukho enyibilikayo emanzini, kwaye idityaniswe nayo. Le ephindeneyo kunqabile kakhulu, nto leyo eyenzeka kuphela ezinqabileyo sukube medium. SO molecule thermodynamically ingazinzi kwaye uguqulwe ekuqaleni S2O2, (ekubhekiselwe disulfur sulphur igesi okanye peroxide). Ngenxa isahlakalo ezinqabileyo ngayo sulphur monoxide-atmosfera yethu kunye nozinzo ophantsi kwemolekyuli kunzima ukuchonga ngokupheleleyo ingozi kweziyobisi. Kodwa a incitshisiwe ngaphezulu okanye wagxila ifomu oxide iba peroxide, nto leyo ityhefu kwaye entsimbini. Le ezimbaxa nayo olunokutsha kakhulu (oku kufana luphawu methane) efunyanwa umlilo nesulfure dioxide - igesi enetyhefu. Isalfure oksayidi Sithole lalimalunga 2 Io (omnye Jupiter Hewana) kwi umoya Venus kunye oluphakathi medium. Kuthathwa ukuba Io, nguye ngenxa yeenkqubo mlilo nomsi. reactions Basic nomsi zezi zilandelayo: O + S2 → S + SO kunye SO2 → SO + O.

sulphur dioxide

Sulphur oxide IV, okanye sulphur dioxide (SO2) yigesi ezingenambala kunye livumba ubhobhoyi elibukhali. Xa amaqondo obushushu thabatha 10 C, iya zibe kwimeko elulwelo kwakunye lobushushu thabatha 73 Ukuguqulwa kolwelo C. Kwi-20 ° C nelitha 1 yamanzi iyachithakala nama-40 komthamo SO2.

Le oxide sulphur esixutywe manzi kabi acid, njengoko acetic yayo: SO2 + H2O ↔ H2SO3.

It esinxibelelana bajula oxides esisiseko: 2NaOH → SO2 + Na2SO3 + H2O kunye SO2 + cao → CaSO3.

Kuba iimpawu ezithile kwe-sulphur dioxide kunye arhente oxidizing kunye arhente nokunciphisa. Oku oxidized yi ioksijini emoyeni ukuya sulphur trioxide phambi ngumnxibelelanisi: SO2 + O2 → 2SO3. Neearhente nokunciphisa ngamandla ezifana emanzini, udlala indima yokuba i oxidant: H2S + SO2 → S + H2O.

Sulphur dioxide isetyenziswa kushishino ubukhulu becala ngenxa ukuveliswa kwe-sulphuric acid. Sulphur dioxide lukhutshwe umlilo nesulfure okanye zentsimbi pyrites: 11O2 + 4FeS2 → 2Fe2O3 + 8SO2.

sulphur trioxide

Sulphur oxide VI, okanye sulphur trioxide (SO3) yi-mveliso eliphakathi kwaye akukho ukubaluleka elizimeleyo. Imbonakalo oko ulwelo enemibala. Abile kubushushu ka 45 C nangezantsi 17 C uguqulwe ube crystalline mass emhlophe. Oku oxides aphezulu sulphur (kunye iqondo igcwala ye atom sulphur + 6) luphawulwa hygroscopicity obukhulu. Amanzi akha sulphuric acid: SO3 + H2O ↔ H2SO4. Unyityilikiswa emanzini, ikhuphe izixa ezikhulu ubushushu, ukuba ungongezi ngokuthe ngcembe, yaye ngoko nangoko isixa enkulu oxide, ngoko-dubulo kungavela. Isalfure trioxide kuba lula enyibilikayo sulphuric acid wamandla ukwakha oleum. Umxholo SO3 of ukuya kutsho kuma-60% oleum. Ngokuba lo sulphur compound luphawulwa zonke iipropati of an oxide asidi.

oxides Higher and asezantsi sulphur

oxides sulphur Higher zenza iqela anemichiza kunye SO3 indlela + x, apho u x unokuba 0 okanye 1. monomer oxide SO4 ezinamaphepha peroxo (OO) lubonakala njengoko oxide SO3, sisidanga nesalfure igcwala +6. Le oksayidi sulphur ingaveliselwa kumaqondo obushushu asezantsi (ngezantsi 78 c) SO3 reaction kunye oxygen-atom okanye photolysis of SO3 kwi umxube kunye ozone.

oxides Lower sulphur zenza iqela anemichiza eziquka:

• SO (sulphur oxide kunye S2O2 yayo dimer);
• S2O;
• monoxides SnO sulphur (ukuba iikhompawundi elibujikele eziquka amakhonkco lisekwa athom isalfure, apho n inokuba ukusuka-5 ukuya kwali-10);
• S7O2;
• oxides sulphur polymeric.

Inzala kwi oxides sulphur ukwanda asezantsi. Oku kungenxa yokuba isidingo ukufunda isiqulatho wabo umoya ezisentlabathini komhlaba.
