Mawonekedwe: ufa woyera kapena pafupifupi woyera kapena kristalo wopanda mtundu

Potaziyamu iodide ndi kristalo woyera kapena ufa. Ndi hygroscopic pang'ono mumlengalenga wonyowa, imatulutsa ayodini kwa nthawi yayitali ndipo imasanduka yachikasu, ndipo imatha kupanga kuchuluka kwa ayodini. Kuwala ndi chinyezi zimatha kufulumizitsa kuwonongeka. 1 g inasungunuka mu 0.7 ml ya madzi, 0.5 ml ya madzi otentha, 22 ml ya ethanol, 8 ml ya ethanol wowira, 51 ml ya ethanol wokwanira, 8 ml ya methanol, 7.5 ml ya acetone, 2 ml ya glycerol, ndi pafupifupi 2.5 ml ya ethylene glycol. Yamadzi ake ndi osalowerera kapena amchere pang'ono ndipo amatha kusungunula ayodini. Yamadzimadziwo amathandizanso kusungunuka ndikusintha kukhala yachikasu, zomwe zingapewedwe powonjezera alkali pang'ono. Kuchuluka kwake ndi 3.12. Kutentha kwa 680 ° C. Kutentha kwa 1330 ° C. Mlingo woopsa (makoswe, mitsempha) unali 285 mg/kg. Amagwiritsidwa ntchito kwambiri pofufuza njira za iodometric pokonzekera mayankho a titration. Zinthu monga Beredes, Modified White, MS, ndi RM zimakonzedwa mu haplotypes. Kufufuza ndowe, ndi zina zotero. Chithunzi. Mankhwala.

Iodide ya potaziyamuNdi gwero la ayodini komanso chowonjezera cha michere ndi zakudya. Imapezeka ngati makhiristo kapena ufa ndipo imasungunuka ndi 1 g mu 0.7 ml ya madzi pa 25°C. Imaphatikizidwa mu mchere wa tebulo kuti ipewe goiter. Potassium Iodide imagwiritsidwa ntchito makamaka pochiza poizoni wa radiation chifukwa cha kuipitsidwa ndi ayodini-131. Imapanganso emulsions yazithunzi; mu chakudya cha nyama ndi nkhuku mpaka magawo 10-30 pa miliyoni; mu mchere wa tebulo ngati gwero la ayodini ndi m'madzi ena akumwa; komanso mu mankhwala a nyama. Mu mankhwala, potaziyamu iodide imagwiritsidwa ntchito kuwongolera chithokomiro.

Potassium iodide idagwiritsidwa ntchito koyamba ngati halide yoyamba mu njira ya Talbot ya calotype, kenako mu njira ya albumen pagalasi kenako njira ya collodion yonyowa. Idagwiritsidwanso ntchito ngati halide yachiwiri mu emulsions ya gelatin ya siliva bromide, chakudya cha ziweto, ma catalyst, mankhwala ojambulira zithunzi, komanso paukhondo. Potassium iodide imapangidwa ndi momwe potaziyamu hydroxide imagwirira ntchito ndi ayodini. Chogulitsacho chimayeretsedwa ndi crystallization kuchokera m'madzi. Potassium iodide ndi mankhwala a ionic omwe ayoni a ayodini ndi ayoni asiliva amatha kupanga iodide yachikasu yokhazikika (ikapezeka pa kuwala, imatha kuwola, ingagwiritsidwe ntchito kupanga filimu yojambulira mwachangu), silver nitrate ingagwiritsidwe ntchito kutsimikizira kupezeka kwa ayoni a ayodini.
