Iron hydroxide 3

The inorganic remubatanidzwa ndiyo simbi hydroxide 3 ane makemikari payakavakirwa Fe (OH) 2. Nderake akatevedzana amphoteric yeimwe esimbi, izvo dzaitongwa ehupfumi kuti anowanzoramba zvigadziko. Tichifunga izvi nefuma iri crystals chena iyo kana mazhinji pakunzwisisa famba zvishoma nezvishoma svibirika. Kune dzakasiyana pamusoro greenish crystals. Muupenyu hwezuva nezuva fuma anogona kuchengeta mumwe muchimiro greenish deposits pamusoro simbi hukawanika, izvo zvinoratidza kutanga kwacho Ngura - simbi hydroxide 3 anoshumira mumwe zvenguva nzendo kwacho.

Hunhu mukomboni vakaita amakinita. Izvi crystalline chicherwa, kunze simbi ine zvakawanda netsvina magnesium uye manganese, zvose izvi zvinhu kupa amakinitu rinoreva zvakasiyana - kubva yero-rwegirini kuti hapana girini, zvichienderana chikamu chimwe chinhu. The neukukutu zvicherwa ndiyo 3.5-4 pamusoro Mohs pamwero zviyero, uye arambe achirema anenge 3 g / cm³.

The ehupfumi of fuma chaiko kunofanira kusanganisira ayo zvikuru pasi solubility. In Kana apo simbi hydroxide 3 neshungu, zvinonzi yaora.

fuma Izvi chaizvo uye interacts pamwe nezvimwe zvinhu uye yeimwe. Saka, somuenzaniso, vane ehupfumi ane nechigadziko, izvozvo anopinda neutralization maitiro pamwe acids zvakasiyana. Zvikurukuru, sulfuric acid, ferric hydroxide 3 panguva wanda kutungamirira kugadzirwa nesimbi sulfate (III). Sezvo izvi zvinogona kuitika nokuda kwakajairika calcination mu pakachena mhepo, zvakadai isingadhuri nzira kubudisa sulphate rinoshandiswa zvose murabhoritari uye maindasitiri runyararo.

Panguva zvakaitwa pamwe hydrochloric acid, ayo mugumisiro ndiye paumbwe simbi chloride (II).

Mune zvimwe zviitiko, simbi hydroxide uye 3 anogona kuratidza asidhi ehupfumi. Saka, somuenzaniso, kuita ane zvikuru kuramba (wevasungwa kunofanira kanenge 50%) yavaibvisa hydroxide inotoda akawana tetragidroksoferrat (II) yavaibvisa kuti precipitate somunhu. Zvisinei, nokuti aibuda chakadaro kuita zvakakodzera kupa zvinhu zvakarurama zvakaoma: maitiro ikaitika iri mhinduro achibika pasi senitrogen mumhepo ezvinhu.

Sezvambotaurwa, kubudikidza muchidziisa fuma uchiora. Mugumisiro kuwedzera ichi anoita se simbi oxide (II), uye, mukuwedzera, sezvo nouipi esimbi simbi vakawana uye nomukaka ayo dizheleza oxide (III), kemikari payakavakirwa ndiye Fe3O4.

Sei kubereka simbi hydroxide 3, kugadzirira uko chokuita nemano ayo kuti sei pamwe acids? Asati kuti ndifambire mberi kuedza, iva nechokwadi kuti kuyeuchidza yakachengeteka mitemo pakuitisa kuedza kwakadaro. mitemo aya nyaya dzose, pakurapa asidhi-alkaline mhinduro. Hunokosha pano - kudzivirira yakavimbika uye kudzivisa ingress mhinduro mumate pamusoro ganda uye mucous membranes.

Saka, munhu anogona kuwana hydroxide panguva maitiro iyo nekutaurirana simbi chloride (III) uye Koh - Potassium hydroxide. nzira iyi - chikonzero rakajairika kuti paumbwe insoluble. In zvakaitwa izvi zvinhu zvinobuda kwakajairika Exchange maitiro, zvichiguma precipitate kwaanoda shava. precipitate Ndicho achida fuma.

Kushandiswa simbi hydroxide ari maindasitiri kugadzirwa nani zvikuru. Rakajairika iri kushandiswa kwayo kutoshanda fuma iri nickel-yesimbi bhatiri mhando. Uyezve, mukomboni inoshandiswa simbi kubudisa siyana ferro alloys, uyewo vari electroforming prizvodstvo, avomobilestroenii.
