Kodi rhodium imachita chiyani?

Metal rhodiumimakhudzidwa mwachindunji ndi mpweya wa fluorine kupanga rhodium (VI) fluoride yowononga kwambiri, RhF6. Nkhaniyi, mosamala, imatha kutenthedwa kuti ipange rhodium(V) fluoride, yomwe ili ndi mawonekedwe ofiira ofiira a tetrameric [RhF5]4.

 

Rhodium ndi chitsulo chosowa komanso chamtengo wapatali chomwe chili m'gulu la platinamu. Amadziwika ndi zinthu zake zapadera, monga kukana kwambiri kwa dzimbiri ndi makutidwe ndi okosijeni, matenthedwe abwino kwambiri amagetsi ndi magetsi, komanso kawopsedwe kakang'ono. Imawunikiranso kwambiri ndipo imakhala ndi mawonekedwe owoneka bwino a silvery-white, ndikupangitsa kuti ikhale yotchuka muzodzikongoletsera ndi zinthu zokongoletsera.

 

Rhodium sagwirizana ndi zinthu zambiri kutentha kwa chipinda, zomwe zimapangitsa kuti zisawonongeke kwambiri ndi dzimbiri. Komabe, monga zitsulo zonse, rhodium imathabe kuchitapo kanthu pazikhalidwe zina. Pano, tikambirana zina mwazochita zomwe rhodium ingakumane nazo.

 

1. Rhodium ndi Oxygen:

Rhodium imakhudzidwa ndi mpweya pa kutentha kwambiri, kupanga rhodium (III) oxide (Rh2O3). Izi zimachitika pamene rhodium yatenthedwa pamwamba pa 400 ° C mumlengalenga. Rhodium (III) oxide ndi ufa wakuda wotuwa womwe susungunuka m'madzi ndi ma acid ambiri.

 

2. Rhodium ndi haidrojeni:

Rhodium imakhudzidwanso ndi mpweya wa haidrojeni pakatentha kwambiri mpaka 600 °C, kupanga rhodium hydride (RhH). Rhodium hydride ndi ufa wakuda womwe umasungunuka pang'ono m'madzi. Zomwe zimachitika pakati pa mpweya wa rhodium ndi wa haidrojeni zimatha kusintha, ndipo ufawo ukhoza kuwolanso kukhala mpweya wa rhodium ndi hydrogen.

 

3. Rhodium ndi Halogens:

Rhodium imakhudzidwa ndi halogens (fluorine, chlorine, bromine, ndi ayodini) kupanga rhodium halides. The reactivity wa rhodium ndi halogens kumawonjezeka kuchokera fluorine kuti ayodini. Rhodium halides nthawi zambiri ndi zolimba zachikasu kapena lalanje zomwe zimasungunuka m'madzi. Za

Mwachitsanzo: Rhodium fluoride,Rhodium (III) ChlorideRhodium bromine,Rhodium ayodini.

 

4. Rhodium ndi Sulfure:

Rhodium imatha kuchitapo kanthu ndi sulfure pa kutentha kwambiri kupanga rhodium sulfide (Rh2S3). Rhodium sulfide ndi ufa wakuda womwe susungunuka m'madzi ndi ma acid ambiri. Amagwiritsidwa ntchito m'mafakitale osiyanasiyana monga ma aloyi azitsulo, mafuta, ndi ma semiconductors.

 

5. Rhodium ndi Acids:

Rhodium imagonjetsedwa ndi asidi ambiri; komabe, imatha kusungunuka mu osakaniza a hydrochloric ndi nitric acid (aqua regia). Aqua regia ndi njira yowononga kwambiri yomwe imatha kusungunula golide, platinamu, ndi zitsulo zina zamtengo wapatali. Rhodium imasungunuka mu aqua regia kupanga ma chloro-rhodium complexes.

 

Pomaliza, Rhodium ndi chitsulo cholimba kwambiri chomwe chimakhala ndi mphamvu zochepa zochitira zinthu zina. Ndi chinthu chamtengo wapatali chomwe chimagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza zodzikongoletsera, zamagetsi, ndi zosinthira zamagalimoto. Ngakhale kuti rhodium imakhala yosasunthika, imatha kuchita zinthu zina zamakina monga oxidation, halogenation, ndi kusungunuka kwa asidi. Ponseponse, chitsulo chapadera ichi chakuthupi ndi mankhwala chimapangitsa kuti chikhale chofunikira kwambiri pazinthu zosiyanasiyana zamafakitale ndi zamalonda.
