Iron hydroxide 3

Egcekeni wezinto kakhulu okusansimbi hydroxide 3 has ifomula amakhemikhali Fe (OH) 2. It kungokwalabo uchungechunge amphoteric compounds yensimbi, okuyinto kubuswa pahla ukuthi kukhona elisekela ejwayelekile. Ngenxa yalokhu ayinto kuyinto zinhlayiya ezimhlophe okuyinto lapho nokunwetshiwe ukuchayeka ngaphandle kancane kancane mnyama. Kunezinhlobo amakristalu ogqamile. Ngo ekuphileni kwansuku zonke izidakamizwa ungakwazi bagcine ngamunye ifomu imali ogqamile Laphezu metal, okhombisa ukuqala inqubo nokugqwala - yensimbi hydroxide 3 ukhonza njengomdala kwelinye izigaba Lesisemkhatsini inqubo.

Ubunjalo kwakwakhe zimi amakinita. Lokhu amaminerali crystalline, ngaphandle yensimbi iqukethe ukungcola ngaphezulu magnesium manganese, zonke lezi izinto ukunikeza amakinitu ezihlukile - kusuka ophuzi kungasho oluhlaza, kuye iphesenti isici esithile. Nobulukhuni amaminerali kuyinto 3.5-4 phezu Mohs esikalini amayunithi, kanye kwabantu mayelana 3 g / cm³.

Izakhiwo ketshezi kufanele futhi ufake solubility yayo eliphansi kakhulu. Esimeni lapho hydroxide yensimbi 3 ukufuthelana, it is ukubola.

Le into iyasebenza kakhulu futhi baxhumana nezinye izinto eziningi ezibangela. Ngakho, ngokwesibonelo, ukuba property isisekelo, lingena le neutralization ukuphendula nge acid ezahlukene. Ikakhulukazi, i-sulfuric acid, hydroxide ferric 3 ngesikhathi ukusabela eziholela ukukhiqizwa yensimbi sulfate (III). Njengoba lesi simo singenzeka ngu calcination ezivamile emoyeni evulekile, ezifana oshibhile indlela yokukhiqiza sulphate isetshenziswa kokubili laboratory kanye ezindaweni zezimboni.

Phakathi ukuphendula hydrochloric acid, yi salo kumiswa yensimbi chloride (II).

Kwezinye izimo, yensimbi hydroxide kanye 3 angase abonise izakhiwo acid. Ngakho, ngokwesibonelo, nge ukusabela nge kanzulu kakhulu (okuhlushwa kufanele okungenani 50%) tetragidroksoferrat isixazululo sodium hydroxide etholwe (II) sodium ukuze kwenze njengoba. Nokho, i-ukugeleza ukusabela ngaleyo ndlela kuyadingeka ukunikeza izimo sasivumela nzima: ukusabela kumele kwenzeke e-isixazululo abilayo ngaphansi nitrogen imvelo ozungeze umhlaba wethu.

Njengoba sekushiwo, ngokubeka amalahle ketshezi ubola. Waba yini umphumela walesi ukunwetshwa uba yensimbi oxide (II), futhi, ngaphezu kwalokho, njengoba ukungcola yensimbi metallic etholwe nemikhiqizo yalo dizheleza oxide (III), amakhemikhali Ifomula Fe3O4.

Kanjani ukukhiqiza yensimbi hydroxide 3, ukulungiswa okuyinto ezihlobene ikhono layo ukuxubana acid? Ngaphambi ukuqhubeka ukuhlola, qiniseka ukukhumbuza imithetho yokuphepha lapho ucwaningo anjalo. Le mithetho zisebenza kuwo wonke amacala, ukwelapha izixazululo acid-ane-alikhali. Okubalulekile lapha - ukunikeza isivikelo futhi ukugwema ingress isixazululo amaconsi esikhumbeni futhi nolwelwesi lwamafinyila.

Ngakho, enye bengathola hydroxide ngesikhathi yokusabela lapho uxhumana yensimbi chloride (III) kanye Koh - potassium hydroxide. Le ndlela - yisizathu esivame kakhulu ukuze kwakhiwe zingaxazululeki. Ekusabeleni yalezi izinto okuphuma ezivamile exchange ukuphendula, okuholela kwenze uphendulela ensundu. Lokhu kwenze kungukuqiniseka oyifunayo.

Ukusetshenziswa yensimbi hydroxide e ukukhiqizwa yezimboni kunalokho kabanzi. Okuvame kakhulu ukusebenzisa kwayo njengoba izidakamizwa okusebenzayo nickel-yensimbi uhlobo ibhethri. Ngaphezu kwalokho, lesi sithako elisetshenziswa yokusansimbi ukukhiqiza Alloys ahlukahlukene ferro, kanye kule prizvodstvo electroforming, avomobilestroenii.
