Ishusho: Ifu y'umweru cyangwa idafite umweru cyangwa ifu ya kristali
Iodate ya potasiyumu ni umunyu ukungahaye kuri iyode hamwe na formula ya KIO3. Mu turere dushyuha kandi duhehereye, umwuka wa iyode uhumekwa na hydrolyze bitewe n’uko iyode ya potasiyumu imeze neza. Ugereranyije na iyode ya potasiyumu, iyode ya potasiyumu irahamye kandi imara igihe kirekire. Ni ikintu gikomeye kibuza iyode ya radiyone kwinjira muri tiroyide.
Imiterere y'ibicuruzwa
Iodate ya potasiyumu ni ifu ya kristu imwe cyangwa iy'umweru idafite ibara. Nta mpumuro. Irashonga mu mazi, irashonga aside, ethylenediamine, ethanolamine, na iyode ya potasiyumu; irashonga gato muri dioxyde ya sulfur y'amazi; ntishonga muri alkoholi na ammonia.
Kristali zitagira ibara cyangwa ifu yera; imiterere ya monoclinic; ubucucike bwa 3.90 g/cm3; ihamye ku bushyuhe busanzwe; ishonga kuri 560 °C igasenyuka igice, isohora ogisijeni; ishonga mu mazi akonje; 4.74 g/100mL kuri 0 °C; gushonga cyane mu mazi abira 32.3 g/100mL kuri 100 °C; ishonga mu gisubizo cya potasiyumu iyode; idashobora gushonga muri alcool na ammonia y'amazi.
Porogaramu
1) Potasiyumu Iodate ni isoko ya iyode ikorwa binyuze mu guhuza iyode na potassium hydroxide. Ni ifu ya crystalline ihamye kurusha iyode. Ifite gushonga kwa 1 g muri 15 ml y'amazi. Ikoreshwa nk'umuti ugabanya ifu vuba; ikoreshwa hamwe na potassium bromate nk'umuti ugabanya ogisijeni mu guhindura poroteyine mu ifu y'umugati ituma umugati urushaho kuba mwiza kandi ukagira imiterere myiza. Ikoreshwa mu guteka.
2) Iodate ya potasiyumu ni umuti ukomeye cyane ushobora gukoreshwa mu gupima imiti myinshi, urugero: benzalkonium chloride, cetrimide, hydralazine hydrochloride, iyode ya potasiyumu, phenylhydrazine hydrochloride, semicarbazide hydrochloride n'ibindi nk'ibyo. Mu bipimo bikwiye by'igerageza, iyode ikorana n'iyode na iyode mu buryo bw'umubare. Ariko, birashishikaje kubona hano ko iodeti ishobora gukorwa neza iyo hari aside organic yuzuye, alcohol n'ibindi bintu byinshi by'umwimerere.
Uburyo bwo kugabanya ogisijeni hakoreshejwe iyode ya potasiyumu buri gihe bushingiye ku ikorwa rya monochloride ya iyode (ICl) mu buryo bw'umuti ukomeye wa aside hydrochloric.
3) Iyode ishobora kongerwa mu munyu mu buryo bwa iyode ya potasiyumu (KI) cyangwa iyode ya potasiyumu (KIO3). Kubera ko KIO3 ifite ubushobozi bwo guhagarara neza iyo hari imyanda y'umunyu, ubushuhe, n'imyobo ipfunyitse, ni yo isabwa.
Iyodeti ya potasiyumu, ikorwa nk'umusaruro wa kabiri, igabanuka hakoreshejwe karubone ikora. Umusaruro utunganywa hakoreshejwe kristali iva mu mazi. Ubundi buryo, iyodeti ya feri (II), itegurwa hakoreshejwe ifu y'icyuma na iyode, ishobora kuvurwa na karubone ya potasiyumu kugira ngo ibone iyode ya potasiyumu. Iyodeti ya potasiyumu yuzuye irashobora gukorwa hakoreshejwe uburyo bwa bicarbonate ya potasiyumu irimo aside hidrodike.
