I-potassium iodide yikristale emhlophe okanye umgubo. I-hygroscopic kancinci emoyeni omanzi, ikhupha i-iodine ekhululekileyo ixesha elide kwaye ijike ibe tyheli, kwaye inokwenza isixa esincinci se-iodine. Ukukhanya kunye nokufuma kunokukhawulezisa ukubola. I-1 g yanyibilika kwi-0.7 ml yamanzi, i-0.5 ml yamanzi abilayo, i-22 ml ye-ethanol, i-8 ml ye-ethanol ebilayo, i-51 ml ye-ethanol epheleleyo, i-8 ml ye-methanol, i-7.5 ml ye-acetone, i-2 ml ye-glycerol, kunye ne-2.5 ml ye-ethylene glycol. Isisombululo sayo samanzi asikhethi cala okanye sine-alkaline kancinci kwaye sinokunyibilikisa i-iodine. Isisombululo samanzi siya kunyibilikisa kwaye sitshintshe sibe nombala otyheli, onokuthintelwa ngokongeza inani elincinci le-alkali. Ubuninzi obuhambelanayo yi-3.12. Ubushushu be-680 ° C. Iqondo lokubila le-1330 ° C. Idosi ebulalayo eqikelelweyo (igundane, umthambo) yayiyi-285 mg/kg. Isetyenziswa kakhulu kuhlalutyo lwe-volumetric lweendlela ze-iodometric ukulungiselela izisombululo ze-titration. Iindlela ezifana neBeredes, Modified White, MS, kunye ne-RM zilungiswa ngee-haplotypes. Uvavanyo lwendle, njl. Ifoto. Pharmaceutical.

I-Potassium IodideIngumthombo we-iodine kunye nesondlo kunye nesongezelelo sokutya. Ikhona njengeekristale okanye umgubo kwaye inokunyibilika kwe-1 g kwi-0.7 ml yamanzi kwi-25°C. Ifakiwe kwityuwa yetafile ukuthintela i-goiter. I-Potassium Iodide isetyenziswa kakhulu kunyango lwetyhefu yemitha ngenxa yongcoliseko lokusingqongileyo yi-iodine-131. Ikwayimveliso yee-emulsions zefoto; ekutyeni kwezilwanyana kunye neenkukhu ukuya kuthi ga kwi-10-30 yeenxalenye kwisigidi; kwityuwa yetafile njengomthombo we-iodine nakwamanye amanzi okusela; nakwikhemistri yezilwanyana. Kwizonyango, i-potassium iodide isetyenziselwa ukulawula i-thyroid gland.

I-potassium iodide yaqala ukusetyenziswa njenge-halide ephambili kwinkqubo ye-calotype kaTalbot, yaza yasetyenziswa kwinkqubo ye-albumen kwiglasi yalandelwa yinkqubo ye-collodion emanzi. Yasetyenziswa kwakhona njenge-halide yesibini kwi-silver bromide gelatin emulsions, ukutya kwezilwanyana, ii-catalysts, iikhemikhali zefoto, kunye nococeko. I-potassium iodide iveliswa yi-reaction ye-potassium hydroxide ene-iodine. Imveliso icocwa nge-crystallization emanzini. I-potassium iodide yi-ionic compound apho ii-iodine ions kunye nee-silver ions zinokwenza i-yellow precipitate silver iodide (xa iveliswa ekukhanyeni, inokubola, ingasetyenziselwa ukwenza ifilimu yefoto ekhawulezayo), i-silver nitrate ingasetyenziselwa ukuqinisekisa ubukho bee-iodine ions.
