Ponahalo: phofo e tšoeu kapa e batlang e le tšoeu kapa kristale e se nang mebala
Potassium iodide ke kristale e tšoeu ea cubic kapa phofo. E na le hygroscopic hanyenyane moeeng o mongobo, e fana ka iodine ea mahala nako e telele 'me e fetoha mosehla,' me e ka etsa palo ea palo ea iodate. Leseli le mongobo li ka potlakisa ho bola. 1 g e qhibilihisoa ka 0.7 ml ea metsi, 0.5 ml ea metsi a belang, 22 ml ea ethanol, 8 ml ea ethanol e belang, 51 ml ea ethanol e feletseng, 8 ml ea methanol, 7.5 ml ea acetone, 2 ml ea glycerol, le e ka bang 2.5 ml ea ethylene. Tharollo ea eona ea metsi ha e nke lehlakore kapa e na le alkaline hanyenyane 'me e ka qhala iodine. Tharollo ea metsi e tla boela e oxidize 'me e fetohe' mala o mosehla, o ka thibeloang ka ho eketsa palo e nyenyane ea alkali. Tekanyo e lekanyelitsoeng ke 3.12. Mocheso oa 680 ° C. Sebaka se belang sa 1330 ° C. Lethal dose le ka bang le bolaeang (rat, vein) e ne e le 285 mg / kg. E sebelisoa haholo tlhahlobong ea volumetric ea mekhoa ea iodometric ho lokisa tharollo ea titration. Medium e kang Beredes, Modified White, MS, le RM e lokiselitsoe ka li-haplotypes. Tlhahlobo ea mantle, joalo-joalo Photo. Pharmaceutical.
