Sulfur dioxide

Sulfur oxide (IV) yana da suna, kuma a hukumance a yi amfani da sinadaran kimiyya - sulfur dioxide, a Bugu da kari, wannan abu kuma ana kiranta sulfur dioxide ko sulfur dioxide. Sulfur oxide (IV) a karkashin al'ada yanayi - wannan gas da ciwon wani launi, da peculiar m wari, wanda shi ne reminiscent na wari da wani wasa a lokacin da ƙonewa.

A gas da aka liquefied ta kara matsa lamba, da yawan zafin jiki ba ya bambanta daga talakawa dakin. The abu ne mai narkewa a cikin ruwa to ba m sulfurous acid. A mataki na ruwa solubility na sulfur dioxide ne a zazzabi na 20 C 11,5 grams na wakili da 100 grams na ruwa. Abin sha'awa, a lokacin da zafin jiki da ta fito, da matakin na solubility na fili rage-rage. Bayan ruwa, sulfur dioxide ne narkewa a cikin ethanol da sulfuric acid. A yanayi, sulfur dioxide, wanda dabara ne SO2, shi ne daya daga cikin abubuwa constituting volcanic gas.

A masana'antu samar da sulfur dioxide dogara ne a kan kai tsaye kona sulfur iya kuma za a shirya ta harbe-harben da gas sulfides, musamman kamar pyrite.

Sulfur dioxide da aka samu da kuma awon hanyoyin. Domin wannan dauki yana da za'ayi a sakamakon sulfites karfi acid. Kamar yadda na asali abu amfani a dakunan gwaje-gwaje da kuma hydrosulfites. Irin wannan dauki da aka ba da lissafi: Na2SO3 + H2SO4 → Na2SO4 + H2SO3. A sakamakon da dauki kamar yadda gani daga lissafi, wani sulfurous acid, wanda saboda ta rashin zaman lafiya nan da nan decomposes zuwa sulfur dioxide da kuma ruwa.

Ƙasa da kayan da ake amfani da wata hanya a cikin abin da tasiri a kan kasa aiki karafa da tsarma sulfuric acid, a cikinsa dauki dole ne a ci gaba da dumama da aiki bayani.

Major sinadaran Properties na wadannan sulfur dioxide.

Sulfur dioxide da ake tunawa a cikin ultraviolet kewayon bakan. An classified a matsayin wani acidic oxide. Kamar yadda muka rigaya muka gani, da sulfur dioxide ne mai narkewa a cikin ruwa, a wani reversible sunadarai dauki.

A gabatarwar da gas a cikin dauki tare da Alkali samar sulfites a general, idan ya faye hali reactivity wannan gas, ya kamata shigar da shi ne quite high. A lokacin halayen fi bayyana rage Properties daga cikin abu, da kuma matakin da sulfur hadawan abu da iskar shaka a lokacin da dauki, ya zama mafi girma.

Hadawan abu da iskar shaka Properties na sulfur dioxide bayyana a lokacin halayen tare da karfi reductants. Alal misali, a cikin masana'antu kansu domin samar da sulfur amfani Hanyar warped a sake gina ta carbon oxide (II).

Sulfur oxide (IV) a cikin sinadaran masana'antu yafi amfani ga samar da sulfuric acid. A general, da aikace-aikace ne sosai m da shubuha. Gaskiyar cewa sulfur dioxide ne mai guba. By inhalation iya samun guba cututtuka su ne ciwon makogwaro, runny hanci, tari. Inhalation sulfur dioxide lalacewar fitar da fiye da shi yana sama da taro na abu. A high yawa na iya faruwa tsanani sakamakon, har zuwa shaƙa, jawabin cuta da kuma huhu edema.

Sulfur oxide (IV) da ake amfani a cikin masana'antun sarrafa kayayyakin abinci, musamman shi ne ba a slaboalkogolnyh abubuwan sha a matsayin hana aifuwa na maza. A cikin yadi masana'antu da shi da ake amfani da matsayin bijiro da batun kafa kashi na wajen domin bleaching wani iri-iri na kayan cewa ba za a iya bleached chlorine mahadi.

A cikin masana'antu da kuma ilimi dakunan gwaje-gwaje sulfur oxide (IV) abubuwa a matsayin sauran ƙarfi ba makawa, amma a cikin wannan hali shi dole ne a tuna da cewa a cikin gas iya ƙunsar impurities na ruwa da kuma SO3, wanda mogtst shafi cikin tsarki da kuma daidai Hakika na dauki a gaban silica. Saboda haka, a cikin wadannan lokuta da gas da aka tsarkake ta wucewa ta tace dauke da mayar da hankali H2SO4, ko da yaushe a cikin rufaffiyar jirgin ruwa.

Saboda m amfani sulfur dioxide ayyukan matsayin daya daga cikin manyan abubuwa da gur yanayi. Musamman m watsi sakamakon konewa na mu saba makamashi - kwal, iskar gas da kuma man fetur. Matsayin mai mulkin, yawancin illa ne ta hanyar hazo, saboda ruwan sama - karshen samfurin ne ba a wani aerosol form.

A halin yanzu, cincirindo wannan gas da aka yi bikin a arewacin yammancin duniya, musamman a kan United States, Ukraine, Yammacin Turai da kuma a yankunan dake yammacin Rasha.
