Qhov sib txawv tseem ceeb ntawm oxidation thiab txo qis yog tias oxidation hais txog qhov poob ntawm electrons thaum txo yog hais txog qhov nce ntawm electrons.
Cov tshuaj tiv thaiv kab mob sib txawv ntawm cov tebchaw sib txawv hu ua redox cov tshuaj tiv thaiv yog tias cov oxidation xeev ntawm reactants txawv ntawm cov khoom. Redox yog luv luv rau kev txo qis-oxidation, uas yog qhov tshwm sim hauv cov tshuaj tiv thaiv tshuaj. Thaum oxidation xa mus rau qhov poob ntawm electrons, kev txo qis yog qhov uas cov electrons rov tshwm sim. Cov tshuaj tiv thaiv no tuaj yeem yooj yim lossis nyuaj, nyob ntawm tus txheej txheem thiab cov atoms koom nrog.
Oxidation yog dab tsi?
Oxidation tuaj yeem piav qhia raws li kev nce hauv oxidation naj npawb. Yog li, oxidation tuaj yeem txhais tau tias yog qhov poob ntawm electrons los ntawm atom, molecule lossis ion. Qhov kev poob ntawm cov hluav taws xob no ua rau lub xeev oxidation ntawm cov tshuaj lom neeg ntau ntxiv. Txij li thaum cov tshuaj tiv thaiv oxidation tso tawm cov hluav taws xob, yuav tsum muaj cov khoom siv hluav taws xob txais. Yog li ntawd, cov tshuaj tiv thaiv oxidation yog ib nrab ntawm cov tshuaj tiv thaiv loj. Lub oxidation ntawm ib hom tshuaj yog muab raws li qhov kev hloov ntawm nws oxidation xeev. Oxidation xeev yog tus lej nrog qhov zoo (+) lossis qhov tsis zoo (-) lub cim, uas qhia txog qhov poob lossis nce ntawm electrons los ntawm ib qho atom, molecule lossis ib qho ion.
Daim duab 01: Ib qho piv txwv ntawm Ob Ib Nrab Kev Sib Tham: Oxidation thiab Txo
Yav dhau los, lo lus oxidation tau muab lub ntsiab lus "qhov sib ntxiv ntawm oxygen rau ib qho chaw."Qhov no yog vim hais tias oxygen yog tib lub npe hu ua oxidizing tus neeg sawv cev thaum lub sijhawm ntawd. Txawm li cas los xij, qhov kev txhais no tsis yog lawm vim tias muaj ntau ntau cov tshuaj tiv thaiv oxidation uas tshwm sim thaum tsis muaj oxygen. Piv txwv li, cov tshuaj tiv thaiv ntawm Magnesium (Mg) thiab Hydrochloric acid (HCl) tsis muaj oxygen, tab sis nws yog cov tshuaj tiv thaiv redox uas suav nrog oxidation ntawm Mg rau hauv Mg2+
Kev txo qis yog dab tsi?
Kev txo qis tuaj yeem piav qhia raws li kev txo qis hauv oxidation naj npawb. Yog li, peb tuaj yeem txhais qhov txo qis raws li qhov nce ntawm electrons los ntawm atom, molecule, lossis ion. Qhov kev nce ntawm electrons no ua rau lub xeev oxidation ntawm cov tshuaj lom neeg tsawg. Txij li thaum txo cov tshuaj tiv thaiv tau txais cov hluav taws xob, yuav tsum muaj cov khoom siv hluav taws xob pub dawb. Yog li ntawd, qhov txo qis cov tshuaj tiv thaiv yog ib nrab ntawm cov tshuaj tiv thaiv loj. Kev txo qis ntawm hom tshuaj yog muab raws li kev hloov pauv ntawm nws cov oxidation xeev.
Yav dhau los, lo lus txo qis tau muab lub ntsiab lus "kev tshem tawm cov pa tawm ntawm qhov sib xyaw."Qhov no yog vim hais tias oxygen yog tib lub npe hu ua oxidizing tus neeg sawv cev thaum lub sijhawm ntawd. Txawm li cas los xij, qhov kev txhais no tsis yog lawm vim tias muaj ntau ntau cov tshuaj tiv thaiv oxidation uas tshwm sim thaum tsis muaj oxygen.
Qhov txawv ntawm Oxidation thiab txo qis yog dab tsi?
Txo thiab oxidation yog cov txheej txheem tshuaj lom neeg koom nrog hauv txhua qhov tshuaj tiv thaiv. Cov no yog ob qho kev tawm tsam. Qhov sib txawv tseem ceeb ntawm oxidation thiab txo qis yog tias oxidation hais txog qhov poob ntawm electrons thaum txo yog hais txog qhov nce ntawm electrons. Thaum oxidation nce tus nqi ntawm qhov zoo (+) kos npe, txo qis nce tus nqi ntawm qhov tsis zoo (-) kos npe.
Summary – Oxidation vs Reduction
Txo thiab oxidation yog cov txheej txheem tshuaj lom neeg koom nrog hauv txhua qhov tshuaj tiv thaiv. Qhov sib txawv tseem ceeb ntawm oxidation thiab txo qis yog tias Oxidation yog hais txog qhov poob ntawm electrons thaum txo yog hais txog qhov nce ntawm electrons.
