Iron hydroxide 3

A inorganic fili ne da baƙin ƙarfe hydroxide 3 yana da sinadaran dabara Fe (OH) 2. A nasa ne jerin amphoteric mahadi baƙin ƙarfe, wanda aka mamaye da kaddarorin da suke da hankula sansanonin. A ra'ayi na wannan abu ne mai farin lu'ulu'u wanda idan tsawo daukan hotuna da waje hankali duhu. Akwai bambance-bambancen karatu na greenish lu'ulu'u. A rayuwar yau da kullum abu iya tsayar kowane a cikin nau'i na greenish adibas a kan karfe saman, wanda ya nuna da farko na aiwatar da tsatsa - baƙin ƙarfe hydroxide 3 hidima a matsayin daya daga cikin matsakaiciyar matakai na aiwatar.

A yanayi na fili ne kamar yadda amakinita. Wannan crystalline ma'adinai, baya baƙin ƙarfe ƙunshi mafi impurities na magnesium da manganese, duk wadannan abubuwa ba amakinitu daban-daban tabarau - daga yellow-kore su kodadde kore, dangane da kaso na musamman kashi. Taurin ma'adinai ne 3.5-4 a kan Mohs sikelin raka'a, da kuma yawa daga game 3 g / cm³.

The jiki Properties na abu ya kamata kuma sun hada da ta musamman low solubility. A cikin akwati inda baƙin ƙarfe hydroxide 3 da aka kona, shi ne bazu.

Wannan abu ne mai aiki da interacts tare da wasu abubuwa da mahadi. Saboda haka, misali, da ciwon da kaddarorin wani tushe, shi shiga cikin neutralization dauki tare da daban-daban acid. A musamman, sulfuric acid, ferric hydroxide 3 a lokacin da halayen kai ga samar na baƙin ƙarfe sulfate (III). Tun da yake wannan dauki zai iya faruwa ta al'ada calcination a bude iska, irin wannan m Hanyar samar da sulphate an yi amfani da duka a cikin dakin gwaje-gwaje da kuma a masana'antu halin wurare.

A lokacin da dauki tare da hydrochloric acid, ta sakamakon haka ne samuwar baƙin ƙarfe chloride (II).

A wasu lokuta, da baƙin ƙarfe hydroxide da kuma 3 iya nuna acid Properties. Saboda haka, misali, ta hanyar maida martani da matuƙar mayar da hankali (taro ya zama a kalla 50%) sodium hydroxide bayani da aka samu tetragidroksoferrat (II) sodium zuwa precipitate matsayin. Duk da haka, domin kwarara daga irin wannan dauki wajibi ne a samar da wani fairly wuya yanayi: dauki kamata faruwa a cikin bayani ruwan karkashin wani nitrogen yanayin.

Kamar yadda aka ambata a riga, ta gasa da abu decomposes. A sakamakon wannan bazuwa abubuwa a matsayin baƙin ƙarfe oxide (II), da kuma, a Bugu da kari, kamar yadda impurities ƙarfe baƙin ƙarfe samu da kuma Kalam dizheleza oxide (III), da sinadaran dabara ne Fe3O4.

Yadda za a samar da baƙin ƙarfe hydroxide 3, da shirye-shiryen da ake alaka da ikon amsa tare da acid? Kafin a ci gaba da gwaje-gwaje, a tabbatar tunatar da aminci dokoki a lokacin da gudanar da wadannan gwaje-gwajen. Wadannan dokoki shafi dukan lokuta, da magani daga acid-alkaline mafita. Muhimmanci a nan - don samar da dogara da kariya da kuma kauce wa ingress bayani droplets a kan fata da kuma mucous membranes.

Saboda haka, wanda zai iya samun hydroxide a lokacin da dauki a cikin abin da samu. Ƙarfe chloride (III) da kuma Koh - Potassium hydroxide. Wannan hanya - ya fi na kowa dalili na samuwar insoluble. A dauki daga cikin wadannan abubuwa fitowa al'ada musayar dauki, sakamakon precipitate jũya launin ruwan kasa. Wannan precipitate ne da ake so abu.

A amfani da baƙin ƙarfe hydroxide a cikin masana'antu samar wajen yadu. Mafi na kowa ne ta amfani kamar yadda aiki abu a cikin wani nickel-baƙin ƙarfe baturi irin. Bugu da ƙari, cikin fili amfani a metallurgy don samar daban-daban ferro gami, kazalika a electroforming prizvodstvo, avomobilestroenii.
