Iron hayidroksayidi 3

Umchiza ezingaphiliyo yi yentsimbi hayidroksayidi 3 unalo ifomula yemichiza Fe (OH) 2. Lukamongameli kuthotho amphoteric iikhompawundi yentsimbi, leyo usoloko kwiipropati ukuba iziseko ekuso. Ngenxa yoku le nto kukho ziikristale ezimhlophe xa wayolula sesichengeni eli phandle kancinane ziyacima. Kukho ezahlukeneyo ziikristale zana. Ngoqobo yobomi bemihla ngemihla nga bagcine nganye ngohlobo iidipozithi ezibuhlazarha, phezu imiphezulu yesinyithi, nto leyo ebonisa ukuqala inkqubo mhlwa - yentsimbi hayidroksayidi 3 lisebenza omnye manqanaba eziphakathi zenkqubo.

Indlela emi ngayo compound njengoko amakinita. Le ezimbiwa crystalline, ngaphandle intsimbi iqulethe ubumdaka ngaphezulu magnesium kunye manganese, zonke ezi zinto ndokunika amakinitu shades ezahlukeneyo - ukusuka mthubi-eluhlaza ukuba lisuke labuna eluhlaza, kuxhomekeke ipesenti into ethile. Yobulukhuni izimbiwa yi 3.5-4 phezu units kwisikali Mohs, kunye ukuxinana malunga 3 g / cm³.

Iimpawu ezibonakalayo ukwimo kufuneka sibandakanye ukunyibilika esezantsi kakhulu. Kwimeko apho hayidroksayidi intsimbi 3 itshiswe, kokuba ibolile.

Le into iyasebenza kakhulu kwaye zisebenzisana kunye nezinye izinto ezininzi kunye nemixube. Ngoko ke, umzekelo, ukuba iimpawu isiseko, ingena lo indlela neutralization kunye asidi ezahlukeneyo. Ngokukodwa, sulphuric acid, hayidroksayidi ferric 3 ngexesha reactions kukhokelela ekuvelisweni of sulfate yentsimbi (III). Ekubeni le yokusabela kwenzeke nge calcination aqhelekileyo umoya evulekileyo, engabizi loo indlela yokuvelisa sulphate isetyenziswa kokubini elebhu kunye kwiindawo zoshishino.

Ngexesha basabela kunye zehydrochloric acid, isiphumo salo ukuyilwa chloride yentsimbi (II).

Kwezinye iimeko, hayidroksayidi yentsimbi 3 kubonisa iipropati acid. Ngoko ke, umzekelo, ngokuthi zakudibana kanzulu kakhulu (ingqalelo kufuneka ibe ubuncinane i-50%) isisombululo sodium hayidroksayidi ifunyenwe tetragidroksoferrat (II) sodium ukuba kwenze njenge. Noko ke, ngokuba ukuhamba sokungamelani lufuneka ukunika iimeko ezithile ezinzima: kufuneka kwenzeke indlela kwi isisombululo abilayo phantsi nitrogen bume komoya.

Njengoko sele kukhankanyiwe, ngokufudumeza iziyobisi abole. Isiphumo sale lwando isebenza yentsimbi oxide (II), kwaye, ngaphezu koko, njengoko ubumdaka zentsimbi sisinyithi wafumana kunye nezakhi zayo dizheleza oxide (III), iikhemikhali ifomyula Fe3O4.

Njani imveliso intsimbi hayidroksayidi 3, ukulungiswa apho ezinxulumene ukukwazi layo azithethelele asidi? Phambi ukuqhubeka ngexesha experiment, qiniseka ukuba kukhunjuzwe imithetho yokhuseleko xa siqhuba ezinjalo imifuniselo. Le migaqo isebenza kuzo zonke iimeko, unyango kwezisombululo acid-obrak. Okubalulekileyo apha - ukubonelela ukhuseleko ezithembekileyo uphephe amathontsi isisombululo ukungena apha esikhumbeni kunye ngenwebu yangaphakathi.

Ngaloo ndlela, umntu unako ukufumana hayidroksayidi ngexesha indlela apho yentsimbi chloride sebenzisana (III) kunye Koh - Ipotaziyam hayidroksayidi. Le ndlela - isizathu ixhaphakileyo ukuze kwakhiwe ezingenakunyibilika. Xa indlela ezi zinto okuphuma indlela exchange eqhelekileyo, nto leyo kwenze iba brawuni. Le kwenze ke into oyifunayo.

Ukusetyenziswa hayidroksayidi intsimbi imveliso mveliso kunokuba ngokubanzi. Avamise kakhulu ukusetyenziswa kwayo nje into esebenzayo uhlobo battery nickel-yentsimbi. Ngaphezu koko, umchiza esetyenziswa yokunyibilikisa isinyithi ukuvelisa aluminium ezahlukeneyo Ferro, kwakunye kwi prizvodstvo electroforming, avomobilestroenii.
