A neutralization cov tshuaj tiv thaiv yog thaum lub acid thiab lub hauv paus teb tsim dej thiab ntsev thiab koom nrog kev sib xyaw ntawm H+ ions thiab OH- ions los tsim dej. Cov neutralization ntawm ib tug muaj zog acid thiab muaj zog puag muaj pH sib npaug rau 7.
Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog lub mis rau nruab nrab?
Qhov sib npaug neutralization ntawm HCl + NaOH muab rau koj H2O + NaCl twb sib npaug vim tias muaj ob moles ntawm H ntawm ob sab, ib mole ntawm Cl ntawm ob sab, ib mole ntawm Na ntawm ob sab, thiab ib mole ntawm O ntawm ob sab.
Kuj Paub, koj ua li cas neutralize NaOH? Yuav kom pov tseg cov kua qaub kom zoo, xws li hydrochloric acid, peb yuav tsum tau neutralize nws. Qhov no tuaj yeem ua tiav los ntawm kev sib txuas cov kua qaub nrog lub hauv paus, xws li sodium hydroxide . Cov kua qaub thiab lub hauv paus ua rau tsim cov tshuaj nruab nrab ntawm cov dej thiab ntsev.
Yog li ntawd, dab tsi yog ib qho piv txwv ntawm cov tshuaj tiv thaiv neutralization?
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.
Dab tsi 2 yam yog tsim los ntawm neutralization?
Cov tshuaj tiv thaiv neutralization tshwm sim thaum ob lub reactants, ib qho kua qaub thiab lub hauv paus, ua ke los tsim cov khoom ntsev thiab dej.

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
Hom tshuaj twg pom nyob rau hauv cov khoom ntawm cov tshuaj tiv thaiv decomposition?
Cov tshuaj tiv thaiv decomposition tshwm sim thaum ib qho reactant tawg mus rau hauv ob lossis ntau yam khoom. Qhov no tuaj yeem sawv cev los ntawm kev sib npaug dav: AB → A + B. Cov piv txwv ntawm cov tshuaj tiv thaiv decomposition muaj xws li kev tawg ntawm hydrogen peroxide rau dej thiab oxygen, thiab kev tawg ntawm cov dej mus rau hydrogen thiab oxygen
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
