Neutralization . Neutralization yog cov tshuaj tiv thaiv ntawm ib qho acid nrog lub hauv paus uas ua rau cov pH tsiv mus rau 7. Nws yog ib qho tseem ceeb txheej txheem uas tshwm sim nyob rau hauv lub neej txhua hnub xws li nyob rau hauv kev kho mob ntawm acid indigestion thiab kho cov acidic av los ntawm ntxiv txiv qaub. Neutralization kuj txav cov pH ntawm alkali nqes mus rau xya
Yog li ntawd, yuav ua li cas rau pH nyob rau hauv ib tug neutralization cov tshuaj tiv thaiv?
Neutralization . 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 a pH sib 7.
Tsis tas li ntawd, yuav ua li cas rau pH thaum cov kua qaub thiab lub hauv paus sib xyaw? Cov tshuaj tiv thaiv neutralization yog thaum ib qho kua qaub thiab a puag react rau tsim ntsev thiab dej thiab nws koom nrog kev sib xyaw ntawm H + ions 0H- los ua dej. Lub neutralization ntawm lub zog puag thiab muaj zog kua qaub muaj ib PH ntawm 7. Lub neutralization ntawm ib tug muaj zog kua qaub thiab tsis muaj zog puag muaj ib PH qis 7.
Ib yam li ntawd, tib neeg nug, yuav ua li cas thaum cov kua qaub ua rau alkali?
Thaum ib acid reacts nrog alkali , ntsev thiab dej yog tsim: kua qaub + alkali → ntsev + dej Ib qho piv txwv: hydrochloric kua qaub + sodium hydroxide → sodium chloride + dej Cov ntsev uas tsim nyob ntawm qhov twg kua qaub thiab qhov twg alkali teb.
Dab tsi cuam tshuam alkali rau ntawm pH ntawm lub pas dej acidic?
Alkali reacts nrog acid rau neutrilise acid, yog li, cov pH ntawm acidic pas dej ua 7.

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
Qhov nqus thiab tso tawm ntawm lub zog cuam tshuam li cas rau qhov kub thiab txias thaum lub sij hawm muaj tshuaj tiv thaiv?
Nyob rau hauv endothermic cov tshuaj tiv thaiv cov enthalpy ntawm cov khoom yog ntau dua cov enthalpy ntawm cov reactants. Vim tias cov tshuaj tiv thaiv tso tawm lossis nqus lub zog, lawv cuam tshuam rau qhov kub ntawm lawv ib puag ncig. Exothermic cov tshuaj tiv thaiv cua sov ua rau lawv ib puag ncig thaum cov tshuaj tiv thaiv endothermic txias rau lawv
Cov tshuaj tiv thaiv zoo li cas thaum cov tshuaj nkag mus rau hauv cov hlab ntsha?
Cov tshuaj tiv thaiv 'systemic' tshwm sim thaum cov tshuaj nkag mus rau hauv cov hlab ntsha los ntawm daim tawv nqaij, qhov muag, qhov ncauj, lossis lub ntsws
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
