Kupanga zithunzi emulsions;mu nyama ndi nkhuku amadyetsa kufika pa 10-30 magawo pa miliyoni;mumchere wamchere monga gwero la ayodini ndi madzi ena akumwa;komanso Mu chemistry ya nyama.Mu mankhwala, potaziyamu iodide amagwiritsidwa ntchito kuwongolera chithokomiro.
Potaziyamu Iodide ndi gwero la ayodini ndi michere ndi zakudya zowonjezera.imakhala ngati makhiristo kapena ufa ndipo imakhala ndi kusungunuka kwa 1 g mu 0.7 ml ya madzi pa 25 ° C.imaphatikizidwa mumchere wamchere pofuna kupewa goiter.Iodide ya potaziyamu imagwiritsidwa ntchito makamaka pochiza poizoni wa poizoni chifukwa cha kuipitsidwa kwa chilengedwe ndi ayodini-131.
Iodide ya potaziyamu ndi kristalo woyera, granule kapena ufa wopangidwa ndi momwe ayodini amachitira ndi njira yotentha ya potaziyamu hydroxide yotsatiridwa ndi crystallization.Amasungunuka kwambiri m'madzi, mowa, ndi acetone.Iodide ya potaziyamu idagwiritsidwa ntchito koyamba ngati halide yayikulu munjira ya Talbot ya calotype, kenako mu albumen pamagalasi otsatiridwa ndi njira yonyowa ya collodion.Anagwiritsidwanso ntchito ngati halide yachiwiri mu siliva bromide gelatin emulsions.
