Fal-celinta Gassing ee budada aluminium
Cudurka gaarka ah ee aluminium waa kaliya 2.7. Xaaladaha caadiga ah, 1.24 L of hydrogen waxaa loo soo saaraa 1 g oo aluminium ah. Sidaa darteed, lacagta la isticmaalay waa yar yahay oo kharashku wuu yar yahay. Wax soo saarka aluminium waa mid ballaaran oo ilkuna waa mid ballaaran. Waxaa loo isticmaalaa soo saarista la taaban karo ee la taaban karo oo waa sahlan tahay in la xakameeyo marka loo eego nidaamka. Waa maaddada ugu badan ee loo adeegsado ee loogu talagalay gedding. Aluminium waa bir aad u firfircoon. Waxay ka falcelin kartaa aashito si ay ugu beddelaan hydrogen aashitada, waxayna sidoo kale ka jawaabi kartaa alkali si ay u samayso alominate. Aluminium birta si fudud ayaa loo qaddariyo si loo sameeyo aluminium oxide hawada. Qaaciddada falcelinta waa sida soo socota:
4O 3O2 2O2O3
Aluminium oxide wuxuu ku xasilloonaa hawada iyo biyaha. Alaabada aluminium ee aan u isticmaalno nolosheena maalinlaha ah waxay leeyihiin filim ilaalin ah oo kahortag ah oo ah aluminium oxide, kaas oo ka hortagaya fidsion dheeraad ah ee aluminium-ka. Si kastaba ha noqotee, aluminium oxide wuxuu ka jawaabi karaa aashitada ama aalad si aashito ah ama aalad aalalig ama alkaline ah si ay u sameeyaan cusbo cusub, baabi'inta lakabka ilaalinta.
Al2o3 6h = 2Al 3h2O
Al2o3 20h- = 2 a12o3 H2O
Aluminium aluminium wuxuu ka jawaabayaa biyo, barakicinta hydrogen-ka biyaha iyo abuurista aluminium hydroxide.
2Al 6h2O = 2Al (OH) 3 3h2 ↑
Dhaqanka aluminiumka gaaska ee aan isticmaalno had iyo jeer waxay leeyihiin dusha sare ee oxidiid, sameynta aluminiumka filim difaac ah oo ka hortagaya aluminium-ka biyaha. Kaliya ka dib markii filimka okside-ka la tirtiro ayaa budada aluminium ah ka falcelin karaa oo ku barokayn karaa hydrogen-ka biyaha. Sidaa daraadeed, waxaan dhahnaa hubka aluminium, oo ah wakiilka gaaska gaaska, kaliya ayaa mari kara jawaab celin gaas ah oo ku saabsan jawi alkaline ah.
Al (OH) 3 Waxaa soo saarta falcelinta aluminium iyo biyuhu waa shey u eg gel-sida gel-ka, laakiin sidoo kale waxay sidoo kale ku milmi karaan xalka alkaline si ay u soo saaraan alamine xalka
Al (OH) 3 Oh- = A1O2- 2h2O
Sidan, jawiga alkaline, aluminium wuxuu si joogto ah uga falceliyaa biyaha si uu u soo saaro hydrogen ilaa aluminiumka birta la cuno.
Ku dhex jira slitry la taaban karo oo la taaban karo, maadada alkaline waa ca (oh) 2. Sidaa darteed, falcelinta budada aluminium iyo biyaha waxaa loo qori karaa sida:
2ca 3ca (oh) 2 6H2O = 3Cao? Al2o3? 6h2O 3H2 ↑
