Ọdịdị: ntụ ntụ ọcha ma ọ bụ nke fọrọ nke nta ka ọ bụrụ ọcha ma ọ bụ kristal enweghị agba

Potassium iodide bụ kristal ọcha ma ọ bụ ntụ ntụ. Ọ na-adị ntakịrị hygroscopic n'ikuku mmiri, na-akpali iodine efu ruo ogologo oge ma na-agbanwe odo odo, ma nwee ike ịmepụta obere iodate. Ìhè na mmiri mmiri nwere ike ime ka ire ere ngwa ngwa. A gbazere 1 g na mmiri 0.7 ml, 0.5 ml nke mmiri ọkụ, 22 ml nke ethanol, 8 ml nke ethanol ọkụ, 51 ml nke ethanol zuru oke, 8 ml nke methanol, 7.5 ml nke acetone, 2 ml nke glycerol, na ihe dị ka 2.5 ml nke ethylene glycol. Mmiri mmiri ya na-anọpụ iche ma ọ bụ obere alkaline ma nwee ike ịgbaze iodine. Mmiri mmiri ahụ ga-emekwa ka ọ dị ọcha ma gbanwee gaa na agba odo odo, nke enwere ike igbochi site na ịgbakwunye obere alkali. Oke njupụta ya bụ 3.12. Okpomọkụ nke 680 ° C. Ebe esi mmiri nke 1330 ° C. Oke ọnwụ dị ka oke (oke, akwara) bụ 285 mg/kg. A na-eji ya eme ihe nke ukwuu na nyocha volumetric nke usoro iodometric iji kwadebe ngwọta titration. A na-akwadebe ọgwụ dịka Beredes, Modified White, MS, na RM n'ụdị haplotypes. Nnyocha nsị, wdg. Foto. Ọgwụ.

Potassium Iodidebụ isi iyi nke ayodiin na ihe mgbakwunye nri. Ọ dị ka kristal ma ọ bụ ntụ ntụ ma nwee ike ịgbaze 1 g na 0.7 ml nke mmiri na 25°C. A na-etinye ya na nnu tebụl maka igbochi goiter. A na-eji potassium iodide eme ihe karịsịa na ọgwụgwọ nke nsị radieshon n'ihi mmerụ gburugburu ebe obibi site na iodine-131. Ọ bụkwa mmepụta nke emulsions foto; na nri anụmanụ na anụ ọkụkọ ruo ihe dị ka akụkụ 10-30 kwa nde; na nnu tebụl dị ka isi iyi nke ayodiin na ụfọdụ mmiri ọṅụṅụ; na kemịkalụ anụmanụ. Na ọgwụ, a na-eji potassium iodide achịkwa gland thyroid.

E ji potassium iodide mee ihe mbụ dị ka halide mbụ na usoro calotype nke Talbot, wee jiri albumen na iko mee ihe, wee jiri usoro collodion mmiri mee ihe. E jikwa ya mee halide nke abụọ na emulsions gelatin silver bromide, nri anụmanụ, ihe na-akpali akpali, kemịkalụ foto, na maka ịdị ọcha. A na-emepụta potassium iodide site na mmeghachi omume nke potassium hydroxide na iodine. A na-eme ka ngwaahịa a dị ọcha site na kristal site na mmiri. Potassium iodide bụ ngwakọta ionic nke iodine ion na ion ọlaọcha nwere ike ịmepụta odo precipitate silver iodide (mgbe e kpughere ya n'ìhè, ọ nwere ike ire ere, enwere ike iji ya mee ihe nkiri foto dị elu), enwere ike iji silver nitrate mee ihe iji chọpụta ọnụnọ nke iodine ion.
