He aha ka hana a rhodium?

Rhodium metalapane pololei me ke kinoea fluorine e hana i ka rhodium(VI) fluoride, RhF6. Hiki ke hoʻomehana ʻia kēia mea me ka mālama ʻana e hana i ka rhodium(V) fluoride, nona ke ʻano tetrameric ʻulaʻula ʻeleʻele [RhF5]4.

 

ʻO Rhodium kahi metala kakaʻikahi a waiwai nui i pili i ka pūʻulu platinum. Ua ʻike ʻia no kāna mau waiwai kūʻokoʻa, e like me ke kūpaʻa kiʻekiʻe i ka corrosion a me ka oxidation, maikaʻi loa ka wela a me ka uila, a me ka haʻahaʻa haʻahaʻa. He mea noʻonoʻo nui a loaʻa iā ia kahi hiʻohiʻona keʻokeʻo keʻokeʻo keʻokeʻo, e lilo ia i mea kaulana i nā mea nani a me nā mea hoʻonaninani.

 

ʻAʻole pane ʻo Rhodium me nā mea he nui i ka lumi wela, ʻo ia ka mea e pale nui ai i ka ʻino. Eia nō naʻe, e like me nā metala a pau, hiki i ka rhodium ke hana i kekahi mau hopena kemika ma lalo o kekahi mau kūlana. Maʻaneʻi, e kūkākūkā mākou i kekahi o nā hopena maʻamau i loaʻa i ka rhodium.

 

1. Rhodium a me Oxygen:

Hoʻopili ʻo Rhodium me ka oxygen i nā wela kiʻekiʻe, e hana ana i ka rhodium (III) oxide (Rh2O3). Hiki kēia hopena ke hoʻomehana ʻia ka rhodium ma luna o 400 °C i ka ea. ʻO Rhodium (III) oxide kahi pauka hina ʻeleʻele ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a me ka hapa nui o nā waikawa.

 

2. Rhodium a me ka hydrogen:

Hoʻopili pū ʻo Rhodium me ke kinoea hydrogen ma nā wela kiʻekiʻe a hiki i 600 °C, e hana ana i ka rhodium hydride (RhH). ʻO Rhodium hydride kahi pauka ʻeleʻele i hiki ke hoʻoheheʻe ʻia i ka wai. Hiki ke hoʻohuli ʻia ka hopena ma waena o ka rhodium a me ke kinoea hydrogen, a hiki i ka pauka ke hoʻoheheʻe hou i loko o ka rhodium a me ke kinoea hydrogen.

 

3. Rhodium a me Halogens:

Hoʻopili ʻo Rhodium me nā halogens (fluorine, chlorine, bromine, a me iodine) e hana i ka rhodium halides. Hoʻonui ka reactivity o ka rhodium me nā halogens mai ka fluorine i ka iodine. ʻO ka Rhodium halides he mau mea melemele a ʻalani paha i hiki ke hoʻoheheʻe ʻia i ka wai. No ka mea

laʻana: Rhodium fluoride,Rhodium(III) Klorida, Rhodium bromine,Rhodium iodine.

 

4. Rhodium a me Sulfur:

Hiki i ka Rhodium ke hana me ka sulfur ma nā wela kiʻekiʻe e hana i ka rhodium sulfide (Rh2S3). ʻO Rhodium sulfide kahi pauka ʻeleʻele i hiki ʻole ke hoʻoheheʻe ʻia i ka wai a me ka hapa nui o nā waikawa. Hoʻohana ʻia ia i nā noi ʻoihana like ʻole e like me nā ʻāpana metala, lubricants, a me nā semiconductor.

 

5. Rhodium a me nā ʻakika:

Kū'ē ka Rhodium i ka nui o nā waikawa; akā naʻe, hiki ke hoʻoheheʻe ʻia i loko o ka hui ʻana o ka waika hydrochloric a me ka nitric acid (aqua regia). ʻO ka Aqua regia kahi hopena corrosive hiki ke hoʻopau i ke gula, platinum, a me nā metala makamae ʻē aʻe. Hoʻoheheʻe maʻamau ka Rhodium i loko o ka wai regia e hana i nā paʻakikī chloro-rhodium.

 

I ka hopena, ʻo Rhodium kahi metala kūʻokoʻa loa i loaʻa ka hopena liʻiliʻi i nā mea ʻē aʻe. He mea waiwai ia i hoʻohana ʻia i nā ʻano noi like ʻole, me nā mea nani, nā mea uila, a me nā mea hoʻololi catalytic no nā kaʻa. ʻOiai ʻo kona ʻano unreactive, hiki i ka rhodium ke hana i kekahi mau hopena kemika e like me ka oxidation, halogenation, a me ka dissolution acid. Ma ke ʻano holoʻokoʻa, ʻo nā waiwai kino a me nā mea kemika o kēia metala he mea makemake nui ia no nā noi ʻoihana like ʻole.
