Ukubukeka: Impuphu emhlophe noma engemhlophe nhlobo/okuqinile okukristalu
I-potassium iodate iyisawoti ecebile nge-iodine enefomula i-KIO3. Ezimweni ezishisayo nezinomswakama, umhwamuko we-iodine ufakwa emanzini ngenxa ye-hygroscopicity ye-potassium iodide. Uma kuqhathaniswa ne-potassium iodide, i-potassium iodate izinzile kakhulu futhi ihlala isikhathi eside. Iyisivimbeli esinamandla sokumuncwa kwe-iodine enemisebe yi-thyroid gland.
Izakhiwo Zomkhiqizo
I-potassium iodate iyikristalu ye-monoclinic engenambala noma i-white crystal powder. Ayinaphunga. Incibilika emanzini, i-asidi encibilikisiwe, i-ethylenediamine, i-ethanolamine, kanye nezixazululo zamanzi ze-potassium iodide; incibilika kancane ku-sulfur dioxide ewuketshezi; ayincibiliki kuma-alcohols kanye ne-ammonia.
Amakristalu angenambala noma impuphu emhlophe; isakhiwo se-monoclinic; ukuminyana okungu-3.90 g/cm3; kuzinzile emazingeni okushisa ajwayelekile; kuyancibilika ku-560°C ngokubola okuyingxenye, kukhulula umoya-mpilo; kuncibilika ngokulingene emanzini abandayo; 4.74 g/100mL ku-0°C; ukuncibilika okukhulu emanzini abilayo okungu-32.3 g/100mL ku-100°C; kuncibilika kusisombululo se-potassium iodide; akuncibiliki ku-alcohol kanye ne-ammonia ewuketshezi.
Isicelo
1) I-Potassium Iodate iwumthombo we-iodine owenziwe ngokuhlanganisa i-iodine ne-potassium hydroxide. iyimpuphu ekristalu ezinzile kakhulu kune-iodide. Inomswakama ongu-1 g ku-15 ml wamanzi. Isetshenziswa njengesithuthukisi senhlama esisebenza ngokushesha; isetshenziswa ne-potassium bromate njenge-oxidizing agent ukuguqula iphrotheni kufulawa wesinkwa ekhuthaza ivolumu yesinkwa nesimo. Isetshenziswa ezitsheni ezibhakiwe.
2) I-Potassium iodate iyi-ejenti enamandla kakhulu yokuxova engasetshenziswa ekuhlolweni kwezinto eziningana zemithi, isibonelo: i-benzalkonium chloride, i-cetrimide, i-hydralazine hydrochloride, i-potassium iodide, i-phenylhydrazine hydrochloride, i-semicarbazide hydrochloride nokunye okunjalo. Ngaphansi kwemingcele efanele yokuhlola, i-iodate isabela ngobuningi nama-iodide kanye ne-iodine. Nokho, kuyathakazelisa ukubona lapha ukuthi ama-titration e-iodate angenziwa ngempumelelo lapho kukhona ama-acid agcwele e-organic, utshwala kanye nezinye izinto eziningi eziphilayo.
Izindlela zokunciphisa i-oxidation nge-potassium iodate zihlala zisekelwe ekwakhekeni kwe-iodine monochloride (ICl) endaweni yesisombululo se-hydrochloric acid esinamandla.
3) I-iodine ingafakwa kusawoti ngesimo se-potassium iodide (KI) noma i-potassium iodide (KIO3). Ngenxa yokuthi i-KIO3 inokuqina okuphezulu lapho kukhona ukungcola kukasawoti, umswakama, kanye nokupakishwa okunezimbobo, iyindlela enconywayo.
I-potassium iodide, eyakhiwa njengomkhiqizo wesibili, incishiswa yi-activated carbon. Umkhiqizo uhlanzwa ngokukristala emanzini. Ngaphandle kwalokho, i-iron (II) iodide, elungiselelwe ngokusebenzisa i-iron powder kanye ne-iodine, ingaphathwa nge-potassium carbonate ukuze kutholakale i-potassium iodide. I-potassium iodide ehlanzekile kakhulu ingalungiswa ngokuphendula kwe-potassium bicarbonate ene-hydriodic acid.
