Sulphur oxide

Sulphur kwasakazwa ungqimba lomhlaba, kuthatha indawo nesithupha phakathi nezinye izakhi. Kwenzeka kokubili isimo khulula, futhi ifomu lesibopho. izakhiwo metallic isici kwalesi sakhi zamakhemikhali. Igama layo Latin «Sulphur», okhonjiswe S. element kufakwe ion ezahlukene compounds equkethe-mpilo kanye / noma i-hydrogen amafomu izinto eziningi okuqondene amakilasi nosawoti acid oxides amaningi ngasinye singase udluliselwe njengoba oxide sulphur ne ukwengeza izinhlamvu emele Valence. isimo namachibi lapho liveza compounds ahlukahlukene +6, +4, +2, 0, -1, -2. Akwaziwa nesibabule oxides nge ezahlukene namachibi uthi. Okuvame kakhulu - ke dioxide nesibabule trioxide. Ngaphansi eyaziwayo kukhona sulphur monoxide, nangaphezulu (ngaphandle SO3) kanye oxides engezansi lesi sici.

sulphur monoxide

Egcekeni wezinto ngokuthi sulphur oxide II, SO, ukubukeka lokhu kwakwakhe yigesi kungekho nto enemibala emihle. Lapho contact nge akusiyo amanzi encibilikayo, futhi iphendula nalo. Le ngxube ivelakancane, okuyinto eyenzeka kuphela ezingavamile naphakathi gaseous. SO molecule thermodynamically engazinzile futhi uguqulwe ekuqaleni S2O2, (okukhulunywa disulfur igesi sulphur noma peroxide). Ngenxa nesenzakalo ezingavamile sulphur monoxide emkhathini wethu nokuzinza ongaphakeme engqamuzaneni kunzima ukukhomba ngokugcwele ingozi efana. Kodwa endaweni ngaphezulu wafingqa noma bagxila ifomu oxide liphenduka peroxide, okuyinto kuqhathaniswa ezinobuthi futhi onakalisayo. Le ngxube wayebuye kakhulu oluvuthayo (lokhu sifana isici methane) is etholwe lomlilo nesibabule dioxide - igesi enobuthi. Sulphur oxide Kutholwe kwaba mayelana 2 Io (omunye Jupiter iziphuphutheki) emkhathini Venus kanye medium interstellar. Kusolwa ukuthi Io, kuwumphumela izinqubo mlilo kanye photochemical. ukusabela Basic photochemical zimi kanje: O + S2 → S + SO kanye SO2 → SO + O.

sulphur dioxide

Sulphur oxide IV, noma i-sulphur dioxide (SO2) iyinhlangano igesi kungenambala ehlome iphunga angafi. At lokushisa lokususa 10 C, iyaqhubeka kusimo liquid ezingeni lokushisa lokususa 73 C osemanzi. Ngezinye 20 ° C ngo-1 litre amanzi ancibilikisa cishe 40 imiqulu SO2.

Lokhu oxide sulphur ancibilikisa amafomu amanzi sulfurous acid, njengoba anhydride yayo: SO2 + H2O ↔ H2SO3.

It baxhumana lezisekelo futhi oxides eziyisisekelo: 2NaOH → SO2 + Na2SO3 + H2O kanye SO2 + Cao → CaSO3.

Ngezindawo ejwayelekile-sulfur dioxide ne-ejenti oxidizing kanye ejenti ukunciphisa. It is oxidized ngu-mpilo asemkhathini ukuba sulphur trioxide ebukhoneni kulethe: SO2 + O2 → 2SO3. Nge-ejenti enamandla ekunciphiseni njenge-hydrogen sulfide, udlala indima oxidant: H2S + SO2 → S + H2O.

Sulphur dioxide isetshenziswa umkhakha ikakhulukazi ukwenziwa sulfuric acid. Sulphur dioxide kuveza lomlilo nesibabule noma yensimbi pyrites: 11O2 + 4FeS2 → 2Fe2O3 + 8SO2.

sulphur trioxide

Sulphur oxide VI, noma nesibabule trioxide (SO3) umkhiqizo Lesisemkhatsini akunancazelo ezimele. Ngokubukeka iwuketshezi kungekho nto enemibala emihle. It amathumba ezingeni lokushisa 45 C no ngezansi 17 C uguqulwe crystalline mass emhlophe. Lokhu oxides ephakeme sulphur (nge degree of namachibi kuyi-athomu ye-sulphur + 6) libhekene hygroscopicity kakhulu. Nge amanzi akha sulfuric acid: SO3 + H2O ↔ H2SO4. Ziyoncibilika emanzini, likhipha esiningi ukushisa futhi, uma kungenjalo engeza kancane kancane, futhi ngokushesha semali oxide ke ukuqhuma kwenzeka. Sulphur trioxide okubonakala kalula encibilikayo kanzulu sulfuric acid ukwakha oleum. okuqukethwe SO3 afika ku 60% oleum. Ngenxa yalesi kwakwakhe sulphur libhekene zonke izindawo i-nitrous ene-asidi.

oxides Ephakeme engezansi sulphur

Ephakeme nesibabule oxides bakha iqembu zamakhemikhali ne SO3 ifomula + x, lapho x kungaba 0 noma 1. SO4 monomer oxide aqukethe peroxo (OO) libhekene njengoba oxide SO3, degree sulphur namachibi +6. Lokhu oxide sulphur zingaba ngaphansi kwamazinga okushisa aphansi (ngezansi 78 C) ku SO3 yokusabela kanye nomoya-mpilo-athomu noma photolysis ka SO3 e ingxube ne-ozone.

Lower nesibabule oxides bakha iqembu zamakhemikhali ehlanganisa:

• SO (sulphur oxide ne dimer yayo S2O2);
• S2O;
• SnO sulphur monoxides (ayizakhi eyindilinga ehlanganisa izindandatho ezakhiwe ngama-athomu nesibabule, lapho n kungenzeka kusuka 5 kuya ku-10);
• S7O2;
• polymeric nesibabule oxides.

Bayalithakasela Isasasa Esinalo ephansi nokwenyuka nesibabule oxides. Lokhu kungenxa nesidingo sokutadisha okuqukethwe kwabo eziphindwe eliwumhlaba futhi ezisemkhathini.
