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

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Yuav ua li cas koj paub yog hais tias ib qho tshuaj tiv thaiv yog decomposition?
Cov tshuaj tiv thaiv decomposition tshwm sim thaum ib qho reactant tawg mus rau hauv ob lossis ntau yam khoom. Nws tuaj yeem sawv cev los ntawm cov kab zauv dav dav: AB → A + B. Hauv kab zauv no, AB sawv cev rau cov reactant uas pib cov tshuaj tiv thaiv, thiab A thiab B sawv cev rau cov khoom ntawm cov tshuaj tiv thaiv
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
Koj ua li cas sib npaug redox cov tshuaj tiv thaiv hauv acidic thiab nruab nrab nruab nrab?
Acid Conditions Solution. Kauj Ruam 1: Sib cais ib nrab cov lus teb. Kauj Ruam 2: Ntsuas cov ntsiab lus uas tsis yog O thiab H. Kauj Ruam 3: Ntxiv H2O kom sib npaug ntawm cov pa. Kauj Ruam 4: Sib npaug hydrogen los ntawm kev ntxiv protons (H +). Kauj Ruam 5: Ntsuas tus nqi ntawm txhua qhov sib npaug nrog electrons. Kauj Ruam 6: Ntsuas cov tshuaj tiv thaiv kom cov electrons sib npaug
