Kodi ayodini amayendetsa magetsi?

Iodine ndi mchere wofunikira pa thanzi la munthu. Koma ilinso ndi mphamvu zamagetsi? Dziwani zambiri za mutu wosangalatsawu mu positi iyi.

ayodini ndi wakuda, wonyezimira, crystalline olimba kutentha firiji ndi kupanikizika. Imagawana malo kumanja kwa tebulo la periodic ndi ma halogen ena. Iodine imagwiritsidwa ntchito pazinthu zosiyanasiyana monga mchere, inki, zopangira, mankhwala ojambula zithunzi, ndi ma LCD.

ayodini si conductor wabwino wa magetsi chifukwa covalent zomangira amagwira ma elekitironi molimba (zomangira pakati pa maatomu awiri ayodini amapanga molekyu ayodini, I2). ayodini ali ndi electronegativity otsika kwambiri ma halogens onse.

Iodine ndi mankhwala omwe amatengedwa kuti si achitsulo ndipo amapezeka makamaka m'madera ena a dziko lapansi, kuphatikizapo nyanja.

Nkhaniyi ikuuzani zamitundu yosiyanasiyana ya ayodini komanso ngati imayendetsa magetsi.

Chifukwa chiyani ayodini ndi kondakitala wopanda magetsi?

Iodine sayendetsa magetsi chifukwa molekyu iliyonse imapangidwa ndi maatomu awiri a ayodini omwe amalumikizidwa pamodzi ndi chomangira chokhazikika chomwe sichingasangalatse mokwanira kusuntha mphamvu zamagetsi.

Kodi ma conductivity a ayodini amasintha bwanji pakati pa olimba ndi madzi?

Komabe, madutsidwe ake sasintha kwambiri pakati olimba ndi madzi. Ngakhale ayodini si conductor wabwino, kuwonjezera pa zinthu zina kumawapangitsa kukhala okonda bwino. Iodine monochloride ndi njira yamphamvu yopangira mawaya a carbon nanotube kuyendetsa magetsi bwino.

Kodi ayodini m'madzi amalipira bwanji?

Iodide ndi mtundu wa ayodini wa ayodini. Ili ndi mlandu woyipa, ngati halogen. I- (electrolyte kapena ion) m'madzi ipangitsa kuti madzi oyera aziyendetsa magetsi.

Ndi insulator yanji yomwe ili yabwino kwa ayodini?

Ngati mutenga ayodini mu mawonekedwe amadzimadzi, ingakhale covalent. Ma covalent compounds ndiwonso otetezera bwino kwambiri, kotero samalola magetsi kudutsa (zomwe zimachitika ma ions akuyenda).

Kodi ayodini ali ndi mphamvu zotani?

Kutentha kwapakati, ayodini wa elemental ndi wakuda wolimba, wonyezimira komanso wosanjikiza. Nthawi zina amapezeka m'chilengedwe ngati mwala kapena mchere, koma nthawi zambiri amapezeka mu mawonekedwe a iodide, anion (I-). Zing'onozing'ono ndizoopsa pang'ono, koma zochuluka ndizowopsa. Mu mawonekedwe ake oyambirira, ayodini amachititsa zilonda zapakhungu, ndipo mpweya wa ayodini (I2) umakwiyitsa maso.

Ngakhale ayodini sangakhale wotakataka ngati fluorine, chlorine, kapena bromine, imapangabe mankhwala okhala ndi zinthu zina zambiri ndipo imawonedwa ngati ikuwononga. ayodini ndi cholimba chomwe sichitsulo koma chimakhala ndi zitsulo (makamaka mawonekedwe ake onyezimira kapena onyezimira). Iodine ndi insulator, monga zambiri zopanda zitsulo, kotero sizimayendetsa bwino kutentha kapena magetsi.

Zowona za ayodini

• Iodine yolimba imawoneka yakuda, koma ndi mtundu wakuda kwambiri wa buluu-violet womwe umafanana ndi mtundu wa ayodini wagasi, wofiirira.
• Iodine ndiye chinthu cholemera kwambiri chomwe zamoyo zimafunikira komanso chimodzi mwazosowa.
• Ma ayodini ambiri omwe amapangidwa chaka chilichonse amagwiritsidwa ntchito ngati chowonjezera pazakudya za ziweto.
• Kugwiritsidwa ntchito koyamba kwa mchere wa iodized kunali ku Michigan mu 1924. Anthu amene ankakhala pafupi ndi nyanja ndi kudya nsomba za m’nyanja ku United States analandira ayodini wokwanira kuchokera ku chilengedwe. Koma pamapeto pake anapeza kuti kusowa kwa ayodini kumawonjezera chiopsezo cha goiter ndi kukula kwa chithokomiro mwa anthu okhala kumidzi. Dziko kuchokera ku mapiri a Rocky kupita ku Great Lakes ndi kumadzulo kwa New York ankatchedwa "crop lamba".
• Homoni ya chithokomiro ndi yofunika kwambiri pakukula kwamaganizo ndi thupi. Popeza kuti chithokomiro chimafuna ayodini kuti apange timadzi ta thyroxine, kusowa kwa ayodini asanabadwe (kuchokera kwa mayi) kapena paubwana kungayambitse vuto la maganizo kapena kusakula bwino kwa mwanayo. Kuperewera kwa ayodini ndi chifukwa chofala kwambiri cha kufooka kwa malingaliro komwe kumatha kukonzedwa. Izi zimatchedwa congenital hypothyroidism, kutanthauza kuti munthu sanakhale ndi timadzi ta chithokomiro chokwanira kuyambira pamene anabadwa.

Monga mukuonera, ayodini ndi kondakitala osauka magetsi. Chifukwa cha izi, imagwiritsidwa ntchito nthawi zambiri ngati gawo la kondakitala wopanda magetsi. Pamene mukuyang'ana zinthu zopanda conductive pazochitika, muyenera kuonetsetsa kuti sizikusokoneza magetsi.

Onani zina mwazolemba zathu pansipa.

• Sucrose imayendetsa magetsi
• Nayitrogeni amayendetsa magetsi
• Mowa wa Isopropyl umayendetsa magetsi
