Potassium iodate ine iodine yakawanda ine fomura yeKIO3. Munzvimbo dzinopisa uye dzine hunyoro, iodine vapor inonyungudika nekuda kwe hygroscopicity ye potassium iodide. Kana ichienzaniswa ne potassium iodide, potassium iodate inogara kwenguva refu uye inogara kwenguva refu. Inovharira zvine simba kutorwa kwe iodine ine radioactive ne thyroid gland.
Zvivakwa zveChigadzirwa
Potassium iodate haina ruvara rwekristaro kana upfu hwekristaro chena. Hainhuwi. Inonyungudika mumvura, inonyungudika acid, ethylenediamine, ethanolamine, uye potassium iodide mumvura; inonyungudika zvishoma mu liquid sulfur dioxide; hainyungudike mualcohols neammonia.
Makristasi asina ruvara kana upfu huchena; chimiro chekiriniki imwe chete; huwandu hwe3.90 g/cm3; inogadzikana patembiricha yakajairwa; inonyunguduka pa560°C nekuora zvishoma, ichiburitsa okisijeni; inonyunguduka zvine mwero mumvura inotonhora; 4.74 g/100mL pa0°C; inonyunguduka zvakanyanya mumvura inopisa 32.3 g/100mL pa100°C; inonyunguduka mu potassium iodide solution; hainyunguduke mualcohol uye liquid ammonia.
Kushandiswa
1) Potassium Iodate itsime reayodini rinogadzirwa nekubatanidza iyodini nepotassium hydroxide. Iupfu hwekristaro hunogadzikana kupfuura iodide. Hunonyungudika kwe1 g mu 15 ml yemvura. Hunoshandiswa semushonga wekugadzirisa mukanyiwa nekukurumidza; Hunoshandiswa nepotassium bromate semushonga wekugadzirisa protein muupfu hwechingwa iyo inosimudzira huwandu hwechingwa uye chimiro. Hunoshandiswa muzvikafu zvakabikwa.
2) Potassium iodate ine simba guru re oxidizing inogona kushandiswa mukuyedza mishonga yakasiyana-siyana, semuenzaniso: benzalkonium chloride, cetrimide, hydralazine hydrochloride, potassium iodide, phenylhydrazine hydrochloride, semicarbazide hydrochloride nezvimwewo. Pasi pema parameter akakodzera ekuyedza, iodate inoshanda nehuwandu hweiodides ne iodine. Zvisinei, zvinonakidza kuona pano kuti ma iodate titrations anogona kuitwa zvinobudirira kana paine saturated organic acids, alcohol nezvimwe zvinhu zvakawanda zve organic.
Nzira dzekuderedza oxidation ne potassium iodate dzinogara dzichienderana nekuumbwa kwe iodine monochloride (ICl) mune hydrochloric acid solution yakasimba.
3) Iodine inogona kuwedzerwa mumunyu muchimiro che potassium iodide (KI) kana potassium iodide (KIO3). Nekuti KIO3 ine kugadzikana kwakanyanya kana paine tsvina yemunyu, hunyoro, uye maburi ekurongedza, ndiyo inokurudzirwa.
Potassium iodide, iyo inoumbwa sechigadzirwa chechipiri, inoderedzwa neactivated carbon. Chigadzirwa chacho chinocheneswa nekristaro kubva mumvura. Neimwe nzira, iodide yesimbi (II), inogadzirwa nekushandisa iron powder neayodini, inogona kurapwa nepotassium carbonate kuti iwane potassium iodide. Iodide yepotassium yakachena kwazvo inogona kugadzirwa nekuita kwepotassium bicarbonate ne hydriodic acid.
