Qhov sib txawv tseem ceeb ntawm iodine thiab potassium iodide yog tias iodine yog tshuaj lom neeg thaum poov tshuaj iodide yog tshuaj lom neeg.
Iodine yog ib qho halogen uas nyob hauv pawg 17 ntawm lub sijhawm ntawm cov ntsiab lus. Ntawm qhov tod tes, poov tshuaj iodide yog cov tshuaj lom neeg uas tsim los ntawm kev sib xyaw ntawm iodine thiab potassium. Yog li ntawd, cov poov tshuaj iodide muaj txiaj ntsig zoo hauv ntau qhov kev lag luam raws li qhov chaw ntawm iodine.
Iodine yog dab tsi?
Iodine yog cov tshuaj lom neeg muaj tus lej atomic 53 thiab cov cim tshuaj I. Nws yog qhov hnyav tshaj plaws halogen ntawm lwm cov halogens. Cov halogens yog pab pawg 17 cov tshuaj lom neeg hauv lub sijhawm teem sijhawm. Tsis tas li ntawd, iodine muaj nyob rau hauv ib qho lustrous, metallic-grey khoom nyob rau hauv chav tsev kub. Txawm li cas los xij, nws tuaj yeem nkag mus rau sublimation los tsim cov roj violet ntawm iodine. Ntxiv mus, ntawm oxidation hais tias iodine tuaj yeem tshwm sim, qhov -1 oxidation yog qhov feem ntau ntawm lawv, uas ua rau iodide anion. Nws yog vim hais tias, iodine muaj ib qho tsis tiav octet nyob rau hauv nws cov electron configuration nyob rau hauv uas nws yuav tsum tau ib tug electron kom tiav lub octet. Tom qab ntawd, thaum nws tau txais ib qho hluav taws xob los ntawm sab nraud, nws tsim -1 oxidation xeev.
Qee qhov tseeb tseem ceeb ntawm iodine yog raws li hauv qab no:
- Atomic naj npawb - 53
- Standard atomic hnyav - 126.9
- Pom - ci ntsa iab, xim hlau-grey khoom
- Electron configuration – [Kr] 4d10 5s2 5p5
- Group – 17
- Lub Sijhawm - 5
- Tshuaj qeb - nonmetal
- melting point yog 113.7 °C
- Boiling point yog 184.3 °C
Daim duab 01: Ib qho piv txwv ntawm Khoom Iodine
Ntxiv mus, iodine yog ib qho muaj zog oxidizer. Feem ntau, nws yog vim nws tsis tiav octet ntawm electron configuration nyob rau hauv uas nws tsis muaj ib tug electron mus sau lub sab nrauv p orbital. Yog li, nws nrhiav ib qho hluav taws xob los ntawm oxidizing lwm hom tshuaj. Txawm li cas los xij, nws yog qhov tsis muaj zog oxidizing tus neeg sawv cev ntawm lwm cov halogens vim nws loj atomic loj.
YPotassium Iodide yog dab tsi?
Potassium iodide yog ib qho inorganic compound thiab zoo li cov khoom dawb thiab raug tsim tawm hauv kev lag luam ntau. Nws yog qhov tseem ceeb tshaj plaws iodide compound vim nws tsis tshua muaj hygroscopic dua li lwm cov iodide tebchaw. Cov tshuaj formula ntawm no compound yog KI.
Qee cov ntsiab lus tseem ceeb ntawm cov tshuaj no yog raws li hauv qab no:
- Tshuaj formula – KI
- Molar mass - 166 g/mol.
- melting point yog 681 °C.
- Boiling point yog 1, 330 °C.
- Nws muaj cov qauv siv lead ua ntawm sodium chloride.
- Tus neeg txo qis qis.
- Kev tsim khoom yog kev lag luam los ntawm kev kho KOH nrog iodine.
Daim duab 02: Ib qho piv txwv ntawm Cov Khoom Uas Muaj Cov Potassium Iodide
Daim ntawv thov tseem ceeb tshaj plaws ntawm KI yog nyob rau hauv daim ntawv ntawm SSKI (saturated tov ntawm poov tshuaj iodide kuj) ntsiav tshuaj. Cov ntsiav tshuaj no tau noj nyob rau hauv kev kho mob xwm txheej ceev ntawm ntau yam mob. Tsis tas li ntawd, SSKI tseem muaj txiaj ntsig zoo rau kev kho mob thaum raug xwm txheej nuclear. Tsis tas li ntawd, KI yog ib qho ntxiv rau iodine deficiency thaum ntxiv rau cov ntsev. Ntxiv mus, peb tuaj yeem siv nws hauv kev lag luam yees duab thiab hauv kev tshawb fawb biomedical.
Qhov txawv ntawm Iodine thiab Potassium Iodide yog dab tsi?
Iodine yog ib yam tshuaj muaj atomic tooj 53 thiab tshuaj cim kuv thaum Potassium iodide yog ib tug inorganic compound thiab tshwm li dawb khoom thiab yog tsim nyob rau hauv kev lag luam ntau ntau. Yog li ntawd, qhov sib txawv tseem ceeb ntawm iodine thiab potassium iodide yog tias iodine yog ib qho tshuaj lom neeg thaum muaj poov tshuaj iodide yog tshuaj lom neeg. Hauv luv luv, iodine ua ke nrog cov poov tshuaj (piv txwv li, KOH) los tsim cov poov tshuaj iodide compound. Raws li lwm qhov sib txawv tseem ceeb ntawm iodine thiab potassium iodide, peb tuaj yeem hais tias iodine muaj lub ntsej muag zoo nkauj, nws yog xim hlau-grey thaum cov poov tshuaj iodide zoo li cov khoom siv dawb.
Tsis tas li ntawd, muaj qhov sib txawv ntawm iodine thiab potassium iodide hauv lawv cov kev siv thiab. Tsis tas li ntawd, muaj ob peb lwm qhov sib txawv ntawm lawv cov tshuaj lom neeg thiab. Cov duab hauv qab no qhia txog qhov sib txawv ntawm iodine thiab potassium iodide hauv daim ntawv tabular.
Summary – Iodine vs Potassium Iodide
Iodine yog halogen tsis tuaj yeem nyob ua ib qho chaw nyob rau hauv tus qauv kub thiab siab tab sis sib txuas nrog lwm cov ntsiab lus los tsim cov tebchaw yooj yim. Li no, nws yog cov cuab yeej no los tsim cov tebchaw uas ua rau nws yog ib qho tseem ceeb heev. Yog li ntawd, qhov sib txawv tseem ceeb ntawm iodine thiab potassium iodide yog tias iodine yog ib qho tshuaj lom neeg thaum muaj poov tshuaj iodide yog tshuaj lom neeg. Iodine ua ke nrog cov poov tshuaj los ua cov poov tshuaj iodide uas yog ib qho tseem ceeb heev uas muaj txiaj ntsig zoo hauv kev lag luam ntau yam. Txawm li cas los xij, iodine isotopes yog qhov txaus ntshai rau tib neeg, tab sis thaum cov iodine no raug coj los ua KI, nws yuav pab tau rau tib neeg. Ntxiv mus, iodine tsis muaj peev xwm ua rau kev puas hlwb thiab goitre, qhov tsis txaus no tau ua tiav los ntawm kev tswj hwm iodine hauv daim ntawv KI.
