Potassium iodate ndi mchere wokhala ndi ayodini wambiri wokhala ndi formula ya KIO3. M'malo otentha komanso achinyezi, nthunzi ya ayodini imasungunuka chifukwa cha hygroscopicity ya ayodini ya potaziyamu. Poyerekeza ndi ayodini ya potaziyamu, iyodini ya potaziyamu ndi yokhazikika ndipo imakhala ndi nthawi yayitali yosungira. Ndi choletsa champhamvu cha ayodini yotengedwa ndi chithokomiro.
Katundu wa Zogulitsa
Potaziyamu iodate ndi ufa wopanda mtundu wa kristalo kapena woyera wa kristalo. Wopanda fungo. Wosungunuka m'madzi, asidi wosungunuka, ethylenediamine, ethanolamine, ndi potassium iodide aqueous solutions; wosungunuka pang'ono mu madzi a sulfure dioxide; wosasungunuka mu alcohols ndi ammonia.
Makristalo opanda mtundu kapena ufa woyera; kapangidwe kake ka monoclinic; kachulukidwe ka 3.90 g/cm3; kokhazikika pa kutentha kwanthawi zonse; kumasungunuka pa 560°C ndikuwola pang'ono, kutulutsa mpweya; kumasungunuka pang'ono m'madzi ozizira; 4.74 g/100mL pa 0°C; kusungunuka kwakukulu m'madzi otentha 32.3 g/100mL pa 100°C; kumasungunuka mu potassium iodide solution; kumasungunuka mu mowa ndi ammonia yamadzimadzi.
Kugwiritsa ntchito
1) Potaziyamu Iodate ndi gwero la ayodini lomwe limapangidwa pophatikiza ayodini ndi potaziyamu hydroxide. Ndi ufa wa kristalo womwe ndi wokhazikika kuposa iyodini. Uli ndi kusungunuka kwa 1 g mu 15 ml ya madzi. Umagwiritsidwa ntchito ngati chowonjezera ufa mwachangu; umagwiritsidwa ntchito ndi potaziyamu bromate ngati chowonjezera oxidizing kusintha mapuloteni mu ufa wa buledi omwe amalimbikitsa kuchuluka ndi mawonekedwe a buledi. Umagwiritsidwa ntchito mu zophika.
2) Potassium iodate ndi mankhwala amphamvu owonjezera okosijeni omwe angagwiritsidwe ntchito poyesa zinthu zingapo zamankhwala, mwachitsanzo: benzalkonium chloride, cetrimide, hydralazine hydrochloride, potassium iodide, phenylhydrazine hydrochloride, semicarbazide hydrochloride ndi zina zotero. Pansi pa magawo oyenera oyesera, iodate imayankha mochuluka ndi iodides ndi ayodini. Komabe, n'zosangalatsa kuona apa kuti ma iodate titrations amatha kuchitika bwino pamaso pa ma organic acids okhuta, mowa ndi zinthu zina zambiri zachilengedwe.
Njira zochepetsera okosijeni pogwiritsa ntchito potaziyamu iodate nthawi zonse zimadalira kupanga ayodini monochloride (ICl) mu njira yamphamvu ya hydrochloric acid.
3) Iodine ikhoza kuwonjezeredwa ku mchere mu mawonekedwe a potassium iodide (KI) kapena potassium iodide (KIO3). Chifukwa KIO3 imakhala yolimba kwambiri ngati pali zinthu zosafunika za mchere, chinyezi, komanso ma phukusi okhala ndi machubu, ndiye njira yabwino kwambiri.
Potaziyamu iodate, yomwe imapangidwa ngati chinthu chachiwiri, imachepetsedwa ndi mpweya wopangidwa. Chogulitsacho chimayeretsedwa ndi crystallization kuchokera m'madzi. Kapenanso, iodide yachitsulo (II), yokonzedwa pogwiritsa ntchito ufa wachitsulo ndi ayodini, imatha kuchiritsidwa ndi potassium carbonate kuti ipeze potassium iodide. Iodide ya potaziyamu yoyera kwambiri ikhoza kukonzedwa pogwiritsa ntchito potassium bicarbonate yokhala ndi hydriodic acid.
