I-potassium iodate yityuwa etyebileyo kwi-iodine enefomyula i-KIO3. Kwimozulu eshushu nefumileyo, umphunga we-iodine uyanyibilikiswa ngenxa ye-hygroscopicity ye-potassium iodide. Xa ithelekiswa ne-potassium iodide, i-potassium iodate izinzile kwaye ihlala ixesha elide. Ingumqobo onamandla wokufunxwa yi-thyroid gland yi-radioactive iodine.
Iipropati zeMveliso
I-potassium iodate yikristale ye-monoclinic engenambala okanye umgubo omhlophe wekristale. Ayinavumba. Iyanyibilika emanzini, i-asidi enyibilikisiweyo, i-ethylenediamine, i-ethanolamine, kunye nezisombululo zamanzi ze-potassium iodide; iyanyibilika kancinci kwi-sulfur dioxide engamanzi; ayinyibiliki kwi-alcohols kunye ne-ammonia.
Iikristale ezingenambala okanye umgubo omhlophe; ulwakhiwo lwe-monoclinic; ubuninzi be-3.90 g/cm3; izinzile kumaqondo obushushu aqhelekileyo; iyanyibilika kwi-560°C ngokubola okuncinci, ikhupha ioksijini; iyanyibilika ngokuphakathi emanzini abandayo; 4.74 g/100mL kwi-0°C; ukunyibilika okukhulu emanzini abilayo yi-32.3 g/100mL kwi-100°C; iyanyibilika kwisisombululo se-potassium iodide; ayinyibiliki kwi-alcohol kunye ne-ammonia engamanzi.
Isicelo
1) I-Potassium Iodate ngumthombo we-iodine eyenziwa ngokuphendula i-iodine kunye ne-potassium hydroxide. Ngumgubo ocwebezelayo ozinzileyo kune-iodide. Unonyibiliko lwe-1 g kwi-15 ml yamanzi. Isetyenziswa njengesiphuculi sentlama esisebenza ngokukhawuleza; Isetyenziswa kunye ne-potassium bromate njenge-oxidizing agent ukuguqula iproteni kumgubo wesonka okhuthaza ubungakanani besonka kunye nokuma kwaso. Isetyenziswa kwiimpahla ezibhakiweyo.
2) I-Potassium iodate yiarhente enamandla kakhulu yokuxoxisa enokusetyenziswa kuvavanyo lwezinto ezininzi zamayeza, umzekelo: i-benzalkonium chloride, i-cetrimide, i-hydralazine hydrochloride, i-potassium iodide, i-phenylhydrazine hydrochloride, i-semicarbazide hydrochloride nezinye izinto ezinjalo. Phantsi kweeparamitha ezifanelekileyo zovavanyo, i-iodate isabela ngobuninzi kunye ne-iodides kunye ne-iodine. Nangona kunjalo, kuyathakazelisa ukubona apha ukuba i-iodate titrations inokwenziwa ngempumelelo xa kukho ii-organic acids ezigcweleyo, utywala kunye nezinye izinto eziphilayo.
Iindlela zokunciphisa i-oxidation nge-potassium iodate zihlala zisekelwe ekwakhiweni kwe-iodine monochloride (ICl) kwisisombululo se-hydrochloric acid esinamandla.
3) I-Iodine ingongezwa kwityuwa ngohlobo lwe-potassium iodide (KI) okanye i-potassium iodide (KIO3). Ngenxa yokuba i-KIO3 inozinzo oluphezulu xa kukho ukungcola kwetyuwa, ukufuma, kunye nokupakishwa okunemingxuma, yindlela ecetyiswayo.
I-potassium iodide, eyenziwa njengemveliso yesibini, incitshiswa yi-activated carbon. Imveliso icocwa nge-crystallization emanzini. Kungenjalo, i-iron (II) iodide, elungiselelwe ngokusebenzisa umgubo wentsimbi kunye ne-iodine, inokuphathwa nge-potassium carbonate ukuze kufunyanwe i-potassium iodide. I-potassium iodide ecocekileyo kakhulu inokulungiswa ngokuphendula kwe-potassium bicarbonate ene-hydriodic acid.
