Milo sulfuric acid

dareere viscous midab, heerkulka karkaraya ah taas oo ah 269,2 ° C, iyo maamuus u gaar ah - 1.83 g / ml Heerkulka (20º) - taasi waa sulfuric acid. barta barafku walax tani waa 10,3ºS kaliya.

Heerka fiirsashada of sulfuric acid inta badan waa sababta keeno adeegsigeeda chemistry iyo waxsoosaarka warshadaha. Sida caadiga ah, waxaa jira laba heer oo asaasi ah caadiga fiirsashada qeybinta, xitaa in dareen adag cilmiyaysan, si loo kala duwo tiro qaban u dhaxeeya waa wax aan macquul aheyn. Sida laga soo xigtay this soocidda qoondeeyey milo acid sulfuric iyo xoog sulfuric acid.

La macaamilka tiro ka mid ah biraha sida birta, zinc, magnesium, walax this soo bandhigtay hydrogen inta lagu guda jiro dareen-celinta. Tusaale ahaan, by ficil leh cadaanyo birta qaadataa meel, kuwaas oo formula, waxaa qoran sida soo socota: Fe + H2SO4 = FeSO4 + H2. Waa in la xusuustaa in acid ee lagu milo sulfuric, taas oo ah waxa lagu gartaa hantida sida oxidizer xoog leh, ficil ahaan ma fal la Biraha hawlqabadkooda ay yar - copper, lacag, dahab ah.

In oxidant xoog leh, xarunta waa awood oksidheeyeyaal liis aad u dheer oo Biraha, hantida taas oo ka dhigaysa waxaa si ballaaran loo isticmaalo beeraha kala duwan ee wax soo saarka warshadaha.

Caadi ahaan, by ficil leh walxaha kiimikaad ahaan firfircoon, sida magnesium sodium ama, iyadoo ay sabab u reaction redox helay ee xabagta baaruudda (IV), iyo haddii Walxaha firfircooni waa biraha, dareen-celin ka dhalanaya soo saarta tayadda hydrogen (H 2 S) iyo baaruud (S ). Kuwani Biraha firfircoon yihiin calcium, potassium, magnesium hore u soo sheegnay iyo kuwo kale.

Anhydrous, haddii kale waxa loo yaqaan, aadka u xoog sulfuric acid, daciif ah ama si xooga ma la macaamilaan Biraha, sida bir ah, maxaa yeelay, birta ayaa hawl kiimikada aad u yar yahay. Natiijada isdhexgalka ay u adeegi karaan oo kaliya dusha formation of iron daawaha ku jiraan, film adag, taas oo ka kooban kiimikada ka mid ah oxides. Tan waxa u sabab xaqiiqada ah in la badhxay sulfuric acid, iyo u xoog badan, kaydin iyo qaadaa weel la doorbidayo ka samaysan birta, titanium, aluminium, nickel.

walax Tani waa ay awoodaan in ay oxidize non-birta, iyo xataa muujiyaan guryaha oxidative ay falcelinta of walxaha qalafsan, waxa ay yihiin wakiilada yareeyo. dabeecadda reactions sida la go'aamiyo heerka uu fiirsashada, taas oo uu leeyahay acid ee sulfuric milo kiis kasta. Dhinaca kale, walax, iyadoo aan loo eegin heerka fiirsashada uu leeyahay dad badan oo ka mid ah guryaha caan ku hantiyeen by acids kale. Tusaale ahaan, waa awood, lalana xiriiro oxides, keeni go'doomin ee cusbada ku. wax la mid ah ka dhaca dhexgalka la hydroxides. Intaa waxaa dheer, milo acid sulfuric, formula ee taas H2SO4 ah, waa xarunta a dibasic, kaas oo sidoo kale foomamka sifo gaar ah oo keliya, waayo, guryaha ay sameeyaan isdhexgal la walxaha kale. falalka ugu weyn ee keeni ee cusbada ee isdhexgalka, kuwaas oo loo sameeyay laba nooc oo dhexdhexaad ah (xoog acid a), cusbada - sulfates oo badhxan si ay u - cusbada acid, hydrosulfates.

Sida horeba loo xusay, milo sulfuric acid - isticmaalka muhiim ah oo baahsan ee wax soo saarka ee warshadaha kiimikada. Codsiga in qaybaha kale ee warshadaha ayaa sidoo kale wajiyo badan. Sidaas darteed, waxaa loo isticmaalaa in soo saaridda macdantaa macmal ah, iyo noocyada kala duwan ee balaastigga, Bacriminta, formaldehyde. guryaha Acid dalbaday in soo saaridda ee qarxa. In warshadaha ee qodniinka- waa lagama maarmaan in ay wax soo saarka ee biraha, laakiin sidoo kale si weyn loo isticmaalaa sida qalajiyaha gaas.

Taagayo of sulfuric acid - sulphate - si firfircoon loo isticmaalo beeraha, warshadaha - in wax soo saarka ee rinjiga, warqad, caag, malaastaan, iyo in ka badan.
