Metallic rhodiuminopindirana yakananga nefluorine gasi kuumba iyo yakanyanya corrosive rhodium(VI) fluoride, RhF6. Nyaya iyi, nekungwarira, inogona kupiswa kuti iite rhodium(V) fluoride, ine rima dzvuku tetrameric chimiro [RhF5]4.
Rhodium isimbi isingawanzo uye yakakosha zvikuru iyo iri yeboka replatinamu. Iyo inozivikanwa neayo akasarudzika zvimiro, senge kupikisa kwakanyanya kune ngura uye oxidation, yakanakisa yekupisa uye magetsi conductivity, uye yakaderera muchetura. Iyo zvakare inotarisisa zvakanyanya uye ine inokatyamadza silvery-chena chitarisiko, ichiiita yakakurumbira zvinhu muzvishongo uye zvekushongedza zvinhu.
Rhodium haibatike nezvinhu zvakawanda patembiricha yekamuri, izvo zvinoita kuti isarambe ichiita ngura. Nekudaro, sesimbi dzese, rhodium inogona kuramba ichiita mamwe makemikari maitiro pasi pemamwe mamiriro. Pano, tichakurukura mamwe maitiro anowanzoitwa rhodium.
1. Rhodium uye Oxygen:
Rhodium inopindirana neokisijeni pakupisa kwakanyanya, ichiita rhodium (III) oxide (Rh2O3). Kuita uku kunoitika kana rhodium ichidziya kupfuura 400 °C mumhepo. Rhodium (III) oxide ipfumbu yakasviba isina kunyungudika mumvura uye akawanda acids.
2. Rhodium neHydrogen:
Rhodium inopindiranawo nehaidhirojeni gasi patembiricha yepamusoro inosvika 600 °C, ichigadzira rhodium hydride (RhH). Rhodium hydride ihupfu nhema inonyungudika zvishoma mumvura. Mhedzisiro pakati perhodium nehydrogen gasi inodzokororwa, uye hupfu hunogona kuora zvakare kuita rhodium uye hydrogen gasi.
3. Rhodium uye Halogens:
Rhodium inopindirana nehalogens (fluorine, chlorine, bromine, uye iodine) kuumba rhodium halides. Iyo reactivity ye rhodium ine halogens inowedzera kubva ku fluorine kuenda kune iodine. Rhodium halides inowanzoita yero kana orenji yakasimba inonyungudika mumvura. For
muenzaniso: Rhodium fluoride,Rhodium (III) Chloride, Rhodium bromine,Rhodium iodine.
4. Rhodium neSulfur:
Rhodium inogona kuita nesarufa patembiricha yepamusoro kuita rhodium sulfide (Rh2S3). Rhodium sulfide ihupfu hutema husinganyunguriki mumvura uye maasidhi mazhinji. Inoshandiswa mune akasiyana maindasitiri ekushandisa senge simbi alloys, lubricant, uye semiconductors.
5. Rhodium uye Acids:
Rhodium inopesana neakawanda acids; zvisinei, inogona kunyungudika mumusanganiswa wehydrochloric uye nitric acids (aqua regia). Aqua regia mhinduro inoparadza zvakanyanya inogona kunyungudutsa goridhe, platinamu, uye mamwe masimbi anokosha. Rhodium inowanzonyungudika mu aqua regia kuita chloro-rhodium complexes.
Mukupedzisa, Rhodium isimbi inodzivirira zvakanyanya ine zvishoma reactivity kune zvimwe zvinhu. Chinhu chakakosha chinoshandiswa mumhando dzakasiyana dzekushandisa, zvinosanganisira zvishongo, zvemagetsi, uye zvinoshandura zvinoshandura mota. Pasinei nekusashanda kwayo, rhodium inogona kuita mamwe maitiro emakemikari akadai seoxidation, halogenation, uye kuparara kweasidhi. Pakazere, iyi yakasarudzika simbi yemuviri nemakemikari zvimiro inoita kuti ive chinhu chinodiwa zvakanyanya kune akasiyana maindasitiri uye ekutengesa maapplication.
