Woipa sulfure

Sulfa okusayidi (IV) ali ndi dzina, komanso mwalamulo ntchito mankhwala sayansi - woipa sulfure, kuwonjezera, mankhwala amatchedwanso sulfure woipa kapena woipa sulfure. Sulfa okusayidi (IV) m'mikhalidwe yachibadwa - mpweya izi opanda mtundu, ndi achilendo fungo zosasangalatsa, amene ali amatikumbutsa fungo la machesi pa nthawi ya poyatsira.

mpweya ndi liquefied amayamba kuthamanga ndi kutentha mwina amasiyana chipinda wamba. thunthu ndi sungunuka m'madzi kupereka wosakhazikika asidi sulfurous. Mlingo wa madzi solubility wa woipa sulfure ndi pa kutentha 20 C 11,5 magalamu a wothandizila pa magalamu 100 a madzi. N'zochititsa chidwi pamene kutentha limatuluka, mlingo wa solubility pawiri la amachepetsa. Kuwonjezera madzi, sulfure woipa ndi sungunuka Mowa ndi asidi sulfuric. Mu chikhalidwe, sulfure dioxide, amene ndiyo njira SO2, ndi mbali amapanga mpweya chiphala.

The mafakitale wa woipa sulfure zochokera woyaka mwachindunji sulfure amakonzekeranso ndi kuwombera sulfides gasi, makamaka monga galasi.

Sulfa woipa analandira ndi njira zasayansi. Pakuti linachepa ikuchitika pa zotsatira za sulfites zidulo amphamvu. Monga mankhwala zofunika ntchito Laboratories ndi hydrosulfites. Zimenezi kwapatsidwa mwa aone kuti pali kuti: Na2SO3 + H2SO4 → Na2SO4 + H2SO3. The chifukwa cha zimene momwe anaonera aone kuti pali, ndi asidi sulfurous, omwe chifukwa cha Kusakhazikika ake yomweyo linawola kuti woipa sulfure ndi madzi.

Zinthu zochepa ntchito njira zimene zimakhudza motani zitsulo layamba acid kuchepetsa sulfuric, m'mene zimene ayenera kupita ndi Kutentha njira ntchito.

Major mankhwala katundu awa woipa sulfure.

Sulfa woipa imatsala mu ultraviolet osiyanasiyana sipekitiramu wa. Iwo zimagawidwa monga ndi okusayidi acidic. Monga taonera kale, woipa sulfure ndi sungunuka m'madzi mu kusintha mankhwala anachita.

Pa oyamba mpweya mu anachita soda opangidwa sulfites ambiri, ngati nalo pa reactivity mpweya ino, tiyenera kuvomereza si mkulu. Pa zochita zambiri akuwonetseredwa kuchepetsa katundu ndi chuma, ndi mlingo wa makutidwe ndi okosijeni sulfure pa zimene, amakhala apamwamba.

Makutidwe ndi okosijeni katundu wa amasonyeza sulfure woipa pa zochita limodzi ndi reductants amphamvu. Mwachitsanzo, mu gawo mafakitale kwa yopanga sulfure ntchito njira amasokoneza pa okusayidi ake kubwezeretsa mpweya (II).

Sulfa okusayidi (IV) makampani mankhwala makamaka ntchito kubala asidi sulfuric. Ambiri, tanthauzo lake amakhudza kwambiri ndi osokoneza. Mfundo yakuti sulfure woipa ndi poizoni. Ndi inhalation mukhoza kupeza chiphe zizindikiro ndi zilonda zapakhosi, chimfine mphuno, chifuwa. Inhalation sulfure woipa kuwonongeka akubweretsa kuposa zinali pamwamba pa ndende ya thunthu. Pa woipa mkulu angayambe mavuto aakulu, mpaka suffocation, lokhudza kulankhula ndi edema m'mapapo mwanga.

Sulfa okusayidi (IV) ntchito makampani chakudya, makamaka ndi alipo mowa slaboalkogolnyh usawonongeke. Makampani nsalu ndi ntchito ngati chinthu constituent wa njira oyeretsa zosiyanasiyana zipangizo kuti sangathe nsaluzi zinkangokhala chlorine mankhwala.

Mu mafakitale ndi maphunziro Laboratories okusayidi sulfure (IV) amachita monga zosungunulira singasiyanitsidwe, koma mu nkhani iyi izi tiyenera kukumbukira kuti mafuta akhoza muli zosafunika wa madzi ndi SO3, amene mogtst bwanji chiyero ndi njira yolondola ya anachita pamaso pa silika. Choncho, mu milandu mpweya lidzayeretsedwa ndi kudutsa fyuluta munali kuikapo maganizo H2SO4, nthawi zonse mu chotengera chatsekedwa.

Chifukwa zochita yaikulu ntchito sulfure woipa monga wa zinthu zikuluzikulu kuipitsa m'mlengalenga. mpweya oopsa kwambiri, makamaka chifukwa kuyaka mphamvu mwachizolowezi athu - malasha, gasi, mafuta. Monga ulamuliro, ambiri a mavuto ndi kudzera mpweya, chifukwa cha Madzi a mvula - mapeto mankhwala alipo mu mawonekedwe aerosol.

Panopa, anthu ambiri apamwamba mpweya izi yokondwerera kumpoto kwa dziko lapansi, makamaka pa United States, Ukraine, kumadzulo kwa Ulaya ndi ku chakum'mawa kwa dziko la Russia.
