Potassium iodide fari ne mai cubic crystal ko foda. Yana da ɗan ƙaramin hygroscopic a cikin iska mai ɗanɗano, yana haɓaka aidin kyauta na dogon lokaci kuma ya zama rawaya, kuma yana iya samar da adadin iodate. Haske da danshi na iya hanzarta bazuwar. 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, kuma game da 2.5 ml na ethylene glycol. Maganin ruwan sa shine tsaka tsaki ko ɗan alkaline kuma yana iya narkar da aidin. Maganin ruwa mai ruwa kuma zai oxidize kuma ya canza zuwa launin rawaya, wanda za'a iya hana shi ta hanyar ƙara ƙaramin alkali. Matsakaicin dangi shine 3.12. Zazzabi na 680 ° C. Wurin tafasa na 1330 ° C. Matsakaicin adadin kisa (bera, jijiya) shine 285 mg / kg. Ana amfani dashi ko'ina a cikin ƙididdigar ƙima na hanyoyin iodometric don shirya mafita na titration. Matsakaici irin su Beredes, Modified White, MS, da RM an shirya su cikin haplotypes. Gwajin fitsari, da dai sauransu Hoto. Magunguna.

Potassium iodideshi ne tushen aidin da abinci mai gina jiki da kari na abinci. yana wanzuwa azaman lu'ulu'u ko foda kuma yana da solubility na 1 g a cikin 0.7 ml na ruwa a 25 ° C. An haɗa shi a cikin gishirin tebur don rigakafin goiter.Potassium iodideana amfani da shi da farko wajen maganin guba na radiation saboda gurɓacewar muhalli ta iodine-131. Har ila yau, ana yin nau'ikan emulsion na hoto; a cikin abincin dabbobi da kaji har zuwa kashi 10-30 a kowace miliyan; a cikin gishirin tebur a matsayin tushen iodine kuma a cikin wasu ruwan sha; Har ila yau, a cikin ilmin sunadarai na dabba. A cikin magani, ana amfani da potassium iodide don daidaita glandar thyroid.
Potassium iodide aka fara amfani da shi a matsayin farko halide a cikin tsarin calotype Talbot, sa'an nan a cikin albumen a kan gilashin tsari bi da rigar collodion tsari. An kuma yi amfani da shi azaman halide na biyu a cikin emulsion na gelatin bromide na azurfa, ciyarwar dabbobi, abubuwan haɓakawa, sinadarai na hoto, da tsafta. Potassium iodide yana samuwa ta hanyar amsawar potassium hydroxide tare da aidin. Ana tsarkake samfurin ta hanyar crystallization daga ruwa. Potassium iodide ne ionic fili wanda aidin ions da azurfa ions iya samar da rawaya precipitate azurfa iodide (lokacin fallasa ga haske, zai iya bazuwa, shi za a iya amfani da su yi high-gudun daukar hoto fim), azurfa nitrate za a iya amfani da su tabbatar da kasancewar iodine ions.
