Cov tsos mob: dawb los yog yuav luag dawb hmoov los yog tsis muaj xim siv lead ua
Potassium iodide yog dawb cubic siv lead ua los yog hmoov. Nws yog me ntsis hygroscopic nyob rau hauv cov huab cua noo, precipitates dawb iodine rau lub sij hawm ntev thiab tig daj, thiab tuaj yeem tsim ib qho kab ntawm iodine. Lub teeb thiab noo noo tuaj yeem nrawm decomposition. 1 g yog yaj nyob rau hauv 0.7 ml ntawm dej, 0.5 ml ntawm boiling dej, 22 ml ntawm ethanol, 8 ml ntawm boiling ethanol, 51 ml ntawm ethanol, 8 ml ntawm methanol, 7.5 ml ntawm acetone, 2 ml ntawm glycerol, thiab txog 2.5 ml ntawm ethylene glycerol. Nws cov tshuaj aqueous yog nruab nrab lossis me ntsis alkaline thiab tuaj yeem yaj iodine. Cov tshuaj aqueous tseem yuav oxidize thiab hloov mus rau xim daj, uas tuaj yeem tiv thaiv tau los ntawm kev ntxiv me me ntawm alkali. Tus txheeb ze ntom ntom yog 3.12. Qhov kub ntawm 680 ° C. Qhov kub ntawm qhov kub ntawm 1330 ° C. Qhov kwv yees li ntawm cov tshuaj tua kab mob (rat, vein) yog 285 mg / kg. Nws yog dav siv nyob rau hauv lub volumetric tsom xam ntawm iodometric txoj kev los npaj titration daws. Cov khoom nruab nrab xws li Beredes, Hloov Kho Dawb, MS, thiab RM tau npaj hauv haplotypes. Kev kuaj Fecal, thiab lwm yam Duab. Tshuaj.

Potassium Iodideyog ib qhov chaw ntawm iodine thiab cov khoom noj khoom haus thiab kev noj haus ntxiv. Nws tshwm sim raws li muaju los yog hmoov thiab muaj ib tug solubility ntawm 1 g ntawm 0.7 ml ntawm dej ntawm 25 ° C. nws muaj nyob rau hauv lub rooj ntsev rau kev tiv thaiv ntawm goiter.Potassium Iodideyog siv feem ntau siv rau hauv kev kho mob ntawm hluav taws xob lom vim ib puag ncig paug los ntawm iodine-131. Nws tseem yog kev tsim cov duab emulsions; nyob rau hauv cov tsiaj thiab nqaij qaib pub rau thaj tsam ntawm 10-30 qhov chaw ib lab; nyob rau hauv lub rooj ntsev raws li ib qhov chaw ntawm iodine thiab nyob rau hauv ib co dej haus; kuj nyob rau hauv tsiaj chemistry. Hauv kev kho mob, potassium iodide yog siv los tswj cov thyroid caj pas.
Potassium iodide yog thawj zaug siv los ua thawj halide hauv Talbot's calotype txheej txheem, tom qab ntawd hauv albumen ntawm cov txheej txheem iav ua raws li cov txheej txheem ntub dej collodion. Nws kuj tau siv los ua cov halide theem nrab hauv cov nyiaj bromide gelatin emulsions, tsiaj pub, catalysts, tshuaj yees duab, thiab kev huv. Potassium iodide yog tsim los ntawm cov tshuaj tiv thaiv ntawm potassium hydroxide nrog iodine. Cov khoom yog purified los ntawm crystallization los ntawm dej. Potassium iodide yog ionic compound uas iodine ions thiab nyiaj ions tuaj yeem tsim daj precipitate silver iodide (thaum pom lub teeb, nws tuaj yeem decompose, nws tuaj yeem siv los ua cov duab thaij duab nrawm), nyiaj nitrate tuaj yeem siv los txheeb xyuas qhov muaj iodine ions.
