Isabela ngantoni irhodium?

Intsimbi yerhodiumidibana ngqo nerhasi yefluorine ukwenza irhodium (VI) fluoride edlayo kakhulu, RhF6. Esi sixhobo, ngokunyamekela, sinokufudunyezwa ukuba senze i-rhodium (V) i-fluoride, enesakhiwo esimnyama esibomvu se-tetrameric [RhF5]4.

 

I-Rhodium yintsimbi enqabileyo kwaye exabiseke kakhulu eyeqela leplatinam. Iyaziwa ngeempawu zayo ezikhethekileyo, njengokuxhathisa okuphezulu kwi-corrosion kunye ne-oxidation, i-thermal kunye ne-conductivity egqwesileyo yombane, kunye netyhefu ephantsi. Ikwabonisa kakhulu kwaye inenkangeleko emangalisayo yesilivere-emhlophe, iyenza ibe yimathiriyeli eyaziwayo kubucwebe kunye nezinto zokuhombisa.

 

I-Rhodium ayisebenzi kwizinto ezininzi kwiqondo lobushushu begumbi, nto leyo eyenza ukuba imelane kakhulu nokuhlwa. Nangona kunjalo, njengazo zonke iintsimbi, i-rhodium isenokuthi iqhubele phambili kwiikhemikhali phantsi kweemeko ezithile. Apha, siza kuxoxa ngezinye zeempendulo eziqhelekileyo ezinokuthi irhodium ifumaneke.

 

1. I-Rhodium ne-Oxygen:

I-Rhodium isabela nge-oksijini kumaqondo aphezulu, yenze i-rhodium (III) oxide (Rh2O3). Oku kusabela kwenzeka xa irhodium ifudunyezwa ngaphezu kwe-400 °C emoyeni. I-Rhodium (III) i-oxide yimpuphu emnyama engwevu enganyibilikiyo emanzini kunye ne-acids ezininzi.

 

2. I-Rhodium neHydrogen:

I-Rhodium iphinda isebenze kunye negesi ye-hydrogen kumaqondo obushushu aphezulu ukuya kuma-600 °C, yenze i-rhodium hydride (RhH). I-Rhodium hydride ngumgubo omnyama onyibilika kancinane emanzini. Ukusabela phakathi kwe-rhodium kunye negesi ye-hydrogen iyabuyiswa, kwaye umgubo unokubola ubuyele kwi-rhodium kunye negesi ye-hydrogen.

 

3. I-Rhodium kunye neeHalogens:

I-Rhodium iphendula kunye ne-halogens (i-fluorine, i-chlorine, i-bromine, kunye ne-iodine) ukwenza i-rhodium halides. I-reactivity ye-rhodium ene-halogens iyanda ukusuka kwi-fluorine ukuya kwi-iodine. I-Rhodium halides idla ngokuba zizinto eziqinileyo ezityheli okanye eziorenji ezinyibilikayo emanzini. Kuba

umzekelo: Rhodium fluoride,I-Rhodium(III) Ikloridiibromine,Iodine yeRhodium.

 

4. Irodi neSulfure:

I-Rhodium inokusabela ngesulfure kumaqondo obushushu aphezulu ukwenza i-rhodium sulfide (Rh2S3). I-Rhodium sulfide ngumgubo omnyama onganyibilikiyo emanzini kunye ne-acids ezininzi. Isetyenziswa kwizicelo ezahlukeneyo zemizi-mveliso ezinje ngealloyi zetsimbi, izinto zokuthambisa, kunye neesemiconductors.

 

5. I-Rhodium kunye ne-Acids:

I-Rhodium ixhathisa kwii-asidi ezininzi; nangona kunjalo, inokunyibilika kumxube we-hydrochloric kunye ne-nitric acid (i-aqua regia). I-Aqua regia sisisombululo esonakalisa kakhulu esinokunyibilikisa igolide, iplatinam, kunye nezinye iintsimbi ezixabisekileyo. I-Rhodium ngokuqhelekileyo inyibilika kwi-aqua regia ukwenza i-chloro-rhodium complexes.

 

Ukuqukumbela, iRhodium sisinyithi esixhathisa kakhulu esinokuphinda sisebenze kwezinye izinto. Yimathiriyeli exabisekileyo esetyenziswa kwizicelo ezahlukeneyo, kubandakanya ubucwebe, i-elektroniki, kunye neziguquli ze-catalytic zeemoto. Ngaphandle kwemeko yayo engasebenziyo, i-rhodium inokuthi ichaphazeleke kwimichiza ethile efana ne-oxidation, i-halogenation, kunye nokuchithwa kwe-asidi. Ngokubanzi, le mveliso yesinyithi yahlukileyo yomzimba kunye neekhemikhali iyenza ibe yinto enqweneleka kakhulu kwizicelo ezahlukeneyo zoshishino kunye nezorhwebo.
