Ib yam li ntawd, redox ib nrab cov tshuaj tiv thaiv yog dab tsi?

A ib nrab cov tshuaj tiv thaiv yog tus oxidation los yog txo tshuaj tiv thaiv ib feem ntawm a tshuaj tiv thaiv redox . A ib nrab cov tshuaj tiv thaiv yog tau los ntawm kev xav txog kev hloov hauv oxidation lub xeev ntawm tus kheej cov khoom koom nrog hauv tshuaj tiv thaiv redox . Ib nrab tshuaj tiv thaiv feem ntau yog siv los ua ib txoj hauv kev sib npaug cov tshuaj tiv thaiv redox.

Tom qab ntawd, lo lus nug yog, koj sau cov tshuaj tiv thaiv oxidation li cas?

  1. KAUJ RUAM 1: Sau ib lub cev sib npaug rau cov tshuaj tiv thaiv.
  2. Kauj Ruam 2: Muab cov lej oxidation rau cov atoms ntawm ob sab ntawm qhov sib npaug.
  3. KAUJ RUAM 3: Txiav txim siab seb cov atoms twg yog oxidized thiab qhov twg raug txo.
  4. KAUJ RUAM 4: Faib cov tshuaj tiv thaiv rau hauv oxidation thiab txo ib nrab-reactions thiab sib npaug cov ib nrab-reactions ib zaug.

Tom qab ntawd, lo lus nug yog, piv txwv li ib nrab ntawm cov tshuaj tiv thaiv yog dab tsi?

Piv txwv : Zn thiab Cu Galvanic cell Ntawm Zn anode, oxidation tshwm sim (cov hlau poob electrons). Qhov no yog sawv cev hauv oxidation hauv qab no ib nrab - tshuaj tiv thaiv (nco ntsoov tias cov khoom siv hluav taws xob nyob rau sab khoom): Zn(s) → Zn2+ + 2 e. Ntawm Cu cathode, kev txo qis yuav tshwm sim (electrons raug txais).

Dab tsi yog qhov tshuaj tiv thaiv redox piav qhia nrog piv txwv?

Ib oxidation-txo ( redox ) tshuaj tiv thaiv yog ib hom tshuaj tshuaj tiv thaiv uas muaj kev hloov ntawm electrons ntawm ob hom. Kev tsim ntawm hydrogen fluoride yog ib qho piv txwv ntawm a tshuaj tiv thaiv redox . Peb tuaj yeem rhuav tshem tshuaj tiv thaiv down mus soj ntsuam cov oxidation thiab txo cov reactants.
