Tsos: dawb los yog yuav luag dawb hmoov lossis siv lead ua xim tsis muaj xim
Potassium iodide yog ib hom siv lead ua los yog hmoov dawb cubic. Nws me ntsis hygroscopic nyob rau hauv huab cua noo, precipitates dawb iodine ntev thiab hloov daj, thiab tuaj yeem tsim ib qho me me ntawm iodate. Lub teeb thiab noo noo tuaj yeem ua rau kom sai decomposition. 1 g tau yaj rau hauv 0.7 ml dej, 0.5 ml dej npau, 22 ml ntawm ethanol, 8 ml ntawm boiling ethanol, 51 ml ntawm absolute ethanol, 8 ml ntawm methanol, 7.5 ml ntawm acetone, 2 ml ntawm glycerol, thiab kwv yees li 2.5 ml ntawm ethylene glycol. Nws cov kua dej yog neutral lossis me ntsis alkaline thiab tuaj yeem yaj iodine. Cov kua dej kuj tseem yuav oxidize thiab hloov mus rau xim daj, uas tuaj yeem tiv thaiv los ntawm kev ntxiv me ntsis alkali. Qhov ceev ntawm qhov sib piv yog 3.12. Qhov kub ntawm 680 ° C. Lub ntsiab lus kub ntawm 1330 ° C. Qhov kwv yees li ntawm kev tuag (nas, vein) yog 285 mg / kg. Nws yog dav siv hauv kev tshuaj xyuas volumetric ntawm iodometric txoj kev los npaj cov tshuaj titration. Cov tshuaj xws li Beredes, Modified White, MS, thiab RM tau npaj ua haplotypes. Kev kuaj quav, thiab lwm yam. Duab. Tshuaj.

Potassium Iodideyog ib qho chaw ntawm iodine thiab cov khoom noj khoom haus thiab cov khoom noj khoom haus ntxiv. nws muaj nyob rau hauv cov siv lead ua los yog hmoov thiab muaj qhov solubility ntawm 1 g hauv 0.7 ml ntawm dej ntawm 25 ° c. nws suav nrog hauv cov ntsev rau kev tiv thaiv ntawm goiter. Potassium Iodide yog siv feem ntau siv rau hauv kev kho mob ntawm kev lom tshuaj lom vim yog kev ua qias tuaj ntawm ib puag ncig los ntawm iodine-131. Nws kuj tseem yog kev tsim cov duab emulsions; hauv tsiaj thiab nqaij qaib pub rau qhov ntau ntawm 10-30 qhov ib lab; hauv cov ntsev ua qhov chaw ntawm iodine thiab hauv qee qhov dej haus; kuj Hauv cov tsiaj chemistry. Hauv tshuaj, potassium iodide yog siv los tswj cov thyroid caj pas.
Potassium iodide thawj zaug siv ua thawj halide hauv Talbot txoj kev calotype, tom qab ntawd hauv cov txheej txheem albumen ntawm iav ua raws li cov txheej txheem collodion ntub. Nws kuj tau siv ua halide theem nrab hauv cov nyiaj bromide gelatin emulsions, pub tsiaj, catalysts, tshuaj photographic, thiab rau kev ntxuav. Potassium iodide yog tsim los ntawm kev sib xyaw ntawm potassium hydroxide nrog iodine. Cov khoom raug ntxuav los ntawm crystallization los ntawm dej. Potassium iodide yog ionic compound uas iodine ions thiab silver ions tuaj yeem tsim cov xim daj precipitate silver iodide (thaum raug lub teeb, nws tuaj yeem decompose, nws tuaj yeem siv los ua zaj duab xis high-speed photographic), silver nitrate tuaj yeem siv los xyuas seb puas muaj iodine ions.
