Mawu Oyamba
Iodine ndi mankhwala okhala ndi chizindikiro cha mankhwala I ndi atomiki nambala 53. Iodine ndi chinthu chosakhala chitsulo chomwe chimapezeka m'chilengedwe m'nyanja ndi m'nthaka. Zotsatirazi ndikulongosola za chikhalidwe, kagwiritsidwe ntchito, kapangidwe ndi chitetezo cha ayodini:
1. Chilengedwe:
-Maonekedwe: ayodini ndi kristalo wa buluu-wakuda, wofala pokhazikika.
- Malo osungunuka: ayodini amatha kusintha mwachindunji kuchoka ku cholimba kupita ku mpweya wa mpweya pansi pa kutentha kwa mpweya, komwe kumatchedwa sub-limation. Malo ake osungunuka ndi pafupifupi 113.7 ° C.
- Malo owira: Malo owira a ayodini pa kuthamanga kwabwino ndi pafupifupi 184.3 ° C.
-Kachulukidwe: Kuchuluka kwa ayodini ndi pafupifupi 4.93g/cm³.
-Kusungunuka: ayodini sasungunuka m'madzi, koma amasungunuka m'madzi ena monga mowa, cyclohexane, ndi zina zotero.
2. Gwiritsani ntchito:
-Munda wamankhwala: ayodini amagwiritsidwa ntchito kwambiri popha tizilombo toyambitsa matenda komanso kutseketsa, ndipo amapezeka kwambiri m'mabala opha tizilombo toyambitsa matenda komanso mankhwala osamalira pakamwa.
-Mafakitale azakudya: Iodine amathiridwa ngati ayodini mumchere wamchere pofuna kupewa matenda a kusowa kwa ayodini, monga goiter.
-Kuyesa kwamankhwala: ayodini amatha kugwiritsidwa ntchito pozindikira kukhalapo kwa wowuma.
3. Njira yokonzekera:
- ayodini amatha kuchotsedwa powotcha udzu wa m'nyanja, kapena pochotsa miyala yomwe ili ndi ayodini pogwiritsa ntchito mankhwala.
- Zomwe zimachitika pokonzekera ayodini ndikuchita ndi ayodini ndi okosijeni (monga hydrogen peroxide, sodium peroxide, etc.) kuti apange ayodini.
4. Zambiri Zachitetezo:
- Iodine ikhoza kukwiyitsa khungu ndi maso pazigawo zazikulu, kotero muyenera kusamala kugwiritsa ntchito zida zodzitetezera, monga magolovesi ndi magalasi, pogwira Iodine.
- ayodini ali ndi kawopsedwe kakang'ono, koma sayenera kumwa kwambiri ayodini kuti apewe poizoni wa ayodini.
- ayodini amatha kutulutsa mpweya wa ayodini wa haidrojeni wapoizoni pa kutentha kwambiri kapena lawi lotseguka, choncho pewani kukhudzana ndi zinthu zoyaka moto kapena ma okosijeni.
