Potassium iodide fari ne mai siffar kubik ko foda. Yana da ɗan hygroscopic a cikin iska mai danshi, yana haifar da rashin aidin na dogon lokaci kuma yana canza launin rawaya, kuma yana iya samar da ɗan ƙaramin adadin iodate. Haske da danshi na iya hanzarta ruɓewa. An narkar da 1 g a cikin 0.7 ml na ruwa, 0.5 ml na ruwan zãfi, 22 ml na ethanol, 8 ml na ethanol mai tafasa, 51 ml na cikakken ethanol, 8 ml na methanol, 7.5 ml na acetone, 2 ml na glycerol, da kimanin 2.5 ml na ethylene glycol. Maganin ruwansa tsaka tsaki ne ko ɗan alkaline kuma yana iya narkar da iodine. Maganin ruwan kuma zai yi oxidize kuma ya canza zuwa launin rawaya, wanda za'a iya hana shi ta hanyar ƙara ƙaramin adadin alkali. Yawan da ya dace shine 3.12. Zafin jiki na 680 ° C. Tafasar 1330 ° C. Kimanin adadin kisa (bera, jijiyar) shine 285 mg/kg. Ana amfani da shi sosai a cikin nazarin girma na hanyoyin iodometric don shirya mafita na titration. Ana shirya magunguna kamar Beredes, Modified White, MS, da RM a cikin haplotypes. Gwajin najasa, da sauransu. Hoto. Magunguna.

Potassium Iodidetushen aidin ne kuma ƙarin sinadarai masu gina jiki da abinci. Yana wanzuwa a matsayin lu'ulu'u ko foda kuma yana da narkewar 1 g a cikin 0.7 ml na ruwa a 25°C. An haɗa shi a cikin gishirin tebur don hana goiter. Ana amfani da potassium iodide galibi wajen magance gubar radiation saboda gurɓatar muhalli ta hanyar iodine-131. Hakanan ana ƙera emulsions na daukar hoto; a cikin abincin dabbobi da kaji har zuwa sassa 10-30 a kowace miliyan; a cikin gishirin tebur a matsayin tushen aidin da kuma a cikin wasu ruwan sha; haka kuma a cikin ilmin sunadarai na dabbobi. A cikin magani, ana amfani da potassium iodide don daidaita glandar thyroid.

An fara amfani da potassium iodide a matsayin babban halide a tsarin calotype na Talbot, sannan a cikin tsarin albumen akan gilashi sannan a bi tsarin collodion mai laushi. An kuma yi amfani da shi azaman halide na biyu a cikin emulsions na gelatin na azurfa bromide, abincin dabbobi, abubuwan kara kuzari, sinadarai na daukar hoto, da kuma don tsafta. Ana samar da potassium iodide ta hanyar amsawar potassium hydroxide tare da iodine. Ana tsarkake samfurin ta hanyar lu'ulu'u daga ruwa. Potassium iodide wani sinadari ne na ionic wanda ions na iodine da ions na azurfa zasu iya samar da rawaya mai narkewa na azurfa iodide (idan aka fallasa shi ga haske, zai iya rugujewa, ana iya amfani da shi don yin fim ɗin daukar hoto mai sauri), ana iya amfani da azurfa nitrate don tabbatar da kasancewar ions na iodine.
