Sulphur dioxide

Sulphur oxide (IV) unegama, futhi yasetshenziswa ngokusemthethweni isayensi yamakhemikhali - sulphur dioxide, ngaphezu, yalolu ketshezi ubizwa nangokuthi i-sulphur dioxide noma i-sulphur dioxide. Sulphur oxide (IV) ngaphansi kwezimo ezivamile - lokhu igesi abangenalo umbala, ne iphunga eyinqaba ezingemnandi, kuyinto okusikhumbuza iphunga ukufana ngesikhathi ukuthungela.

Le gesi is kuncibilike ngokwandisa ingcindezi, izinga lokushisa angeke zihluke ekamelweni abavamile. Ingqikithi kuyinto oncibilikayo emanzini ukunikeza engazinzile sulfurous acid. Izinga lamanzi solubility-sulfur dioxide kuyinto ezingeni lokushisa 20 C 11,5 amagremu ejenti ngayinye amagremu 100 amanzi. Ngokuthakazelisayo, lapho izinga lokushisa likhuphuka, lizinga solubility of kwakwakhe incipha. Ngaphandle kwamanzi, i-sulphur dioxide kuyinto oncibilikayo ethanol futhi sulfuric acid. Emvelweni, i-sulphur dioxide, ogama Ifomula SO2, ingenye izakhi akha igesi mlilo.

Ukukhiqizwa yezimboni-sulfur dioxide esekelwe esivuthayo oqondile sulphur kungase futhi uzilungiselele ngokudutshulwa le sulfides igesi, ikakhulukazi ezifana pyrite.

Sulphur dioxide etholwe nezindlela laboratory. Ngenxa yalesi ukuphendula Kwenziwa on imiphumela sulfites acid eqinile. Njengoba kungezona lezo eziyisisekelo elisetshenziswa laboratories hydrosulfites. ukusabela okunjalo sinikezwa kwesibalo: Na2SO3 + H2SO4 → Na2SO4 + H2SO3. Waba yini umphumela wesibindi ukusabela njengoba kubonakala kusukela equation, a sulfurous acid, okuyinto ngenxa ukuntengantenga yayo ngokushesha ubola ukuba sulphur dioxide namanzi.

ukwaziswa okuncane isetshenziselwa indlela lapho nomthelela izinsimbi kancane esebenzayo nge alulaze sulfuric acid, lapho ukusabela kumelwe uqhubeke ngokubeka amalahle ikhambi zokusebenza.

Okukhulu chemical izakhiwo zalezi sulphur dioxide.

Sulphur dioxide amuncwa umzimba ku uhla ultraviolet bohlu. It is labizwa ngokuthi i-nitrous ene-asidi. Njengoba sekuphawuliwe kakade, dioxide sulphur kuyinto oncibilikayo emanzini ngendlela esethola chemical yokusabela.

Ngesikhathi ukwethulwa igesi ku ukusabela nge alikhali ekhiqizwa sulfites ngokuvamile, uma kuya njani reactivity lokhu igesi, kufanele alivume impela high. Phakathi ukusabela ngokuvamile abonisa ngayo ukunciphisa izakhiwo ketshezi, kanye nezinga sulphur namachibi phakathi ukuphendula, iba ephakeme.

Namachibi izakhiwo sulphur dioxide sibonisa phakathi ukusabela ephelezelwa reductants eqinile. Ngokwesibonelo, endaweni yezimboni ukwenziwa sulphur wasebenzisa indlela asesonte ngesikhathi sokubuyiselwa carbon yayo oxide (II).

Sulphur oxide (IV) embonini chemical ikakhulu esetshenziswa ukukhiqiza sulfuric acid. Ngokuvamile, uhlelo lwayo lokusebenza ubanzi kakhulu futhi edidayo. Iqiniso lokuthi e-sulfur dioxide kuyinto anobuthi. Ngu ephefumula ungathola izimpawu ushevu kukhona umphimbo obuhlungu, amakhala yisisu, ukukhwehlela. Inhalation umonakalo sulphur dioxide iletha ngaphezu kwalokho okuke kwabonwa ngenhla lokuhlushwa ketshezi. Ngezinye lokuhlala eliphezulu singenzeka nemiphumela emibi ngendlela efanayo, kuze kufinyelele ukufuthelana, inkulumo iziyaluyalu futhi edema yamaphaphu.

Sulphur oxide (IV) isetshenziswa endaweni yokudla, ikakhulukazi kuba khona kunoma iziphuzo slaboalkogolnyh njengoba uyalondoloza. Basembonini yendwangu isetshenziswa njengoba isici abamelwe izindlela for mhlophe ezihlukahlukene izinto ezingeke bleached chlorine compounds.

Laboratories ezimbonini kanye zezemfundo sulphur oxide (IV) uba kuphela esisemqoka, kodwa kulokhu kumelwe kukhunjulwe ukuthi igesi ingaqukatha ukungcola kwamanzi kanye SO3, okuyinto mogtst kuthinte nobumsulwa inkambo efanele yokusabela ebukhoneni Silica. Ngakho-ke, kulezi zimo gas kuhlanzwe edabula isihlungi equkethe kanzulu H2SO4, njalo esitsheni evaliwe.

Ngenxa ebanzi ukusetshenziswa sulphur dioxide izenzo njengoba omunye izinto ezinkulu engcolisa umkhathi. kwekhabhoni ikakhulukazi eziyingozi okubangelwa amandla omlilo of evamile amandla ethu - amalahle, irhasi yemvelo nezinye uwoyela. Njengomthetho, iningi engemihle iwukusebenzisa kwezulu, ngenxa amanzi emvula - okwaphuma lapho kuyilo ekhona ifomu aerosol.

Okwamanje, emakamu oyinhloko walo igesi lugujwa Nenkabazwe, ikakhulu kuyi-United States, e-Ukraine, eNtshonalanga Yurophu nasemazweni ezindaweni entshonalanga Russia.
