neutralization , tshuaj tshuaj tiv thaiv Raws li Arrhenius txoj kev xav ntawm acids thiab bases, nyob rau hauv uas ib tug dej tov ntawm acid yog tov nrog ib tug dej tov ntawm lub hauv paus los ua ib tug ntsev thiab dej; qhov no tshuaj tiv thaiv yog ua kom tiav tsuas yog yog hais tias cov kev daws teeb meem tsis muaj acidic los yog cov yam ntxwv.
Ntawm no, piv txwv li neutralization tshuaj tiv thaiv yog dab tsi?
Neutralization Reaction . Neutralization yog ib hom tshuaj tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag teb nrog rau ib leeg los tsim dej thiab ntsev. Bee stings yog acidic nyob rau hauv cov xwm, uas yog vim li cas ib tsev neeg kho rau ib tug muv sting yog ci dej qab zib los yog sodium bicarbonate, uas yog ib tug yooj yim tshuaj.
Tsis tas li ntawd, qhov sib npaug ntawm cov tshuaj tiv thaiv neutralization yog dab tsi? A kev sib npaug neutralization yog tshuaj tshuaj tiv thaiv uas muaj kev sib xyaw ua ke ntawm cov kua qaub muaj zog thiab lub hauv paus muaj zog. Cov khoom ntawm xws li a tshuaj tiv thaiv feem ntau yog dej thiab ntsev. Cov tshuaj qauv rau hydrochloric acid yog HCl thiab tshuaj qauv rau sodium hydroxide yog NaOH.
Tom qab ntawd, koj yuav txheeb xyuas qhov kev tawm tsam tsis zoo li cas?
A neutralization yog kev hloov pauv ob zaug tshuaj tiv thaiv uas ib yam ntawm cov khoom yog dej. Hauv ib neutralization cov tshuaj tiv thaiv , yuav muaj "H" nyob rau hauv ib qho reactant thiab "OH" nyob rau hauv lwm reactant. Ib qho ntawm cov khoom yuav dej, H-OH (H2O).
Cov piv txwv ntawm Neutralization yog dab tsi?
Nov yog qee txoj hauv kev siv neutralization:
- Cov neeg ua liaj ua teb siv txiv qaub (calcium oxide) los ua kom cov av acidity.
- Koj lub plab muaj hydrochloric acid, thiab ntau dhau ntawm qhov no ua rau plab zom mov. Cov ntsiav tshuaj Antacid muaj cov hauv paus xws li magnesium hydroxide thiab magnesium carbonate kom tsis txhob muaj cov kua qaub ntxiv.
- Bee stings yog acidic.

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
Cov tshuaj twg yog ib txwm tsim los ntawm cov tshuaj tiv thaiv neutralization?
Cov tshuaj tiv thaiv acid-base neutralization ib txwm ua rau ntsev. Qee zaum dej tsuas yog tsim cov tshuaj tiv thaiv uas muaj cov ntses bass thaj tsam muaj zog. Yog li cov lus teb yog ntsev
Dab tsi yog qhov tseeb ntawm cov ntsev tsim nyob rau hauv cov tshuaj tiv thaiv neutralization ntawm hydrochloric acid nrog barium hydroxide?
Lus Nug: Dab tsi yog cov qauv ntawm cov ntsev tsim nyob rau hauv Neutralization Reaction ntawm Hydrochloric Acid Nrog Barium Hydroxide? BaCl BaCl2 BaClH BaH2 BaO
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
