Cov tshuaj tiv thaiv ntawm ib kua qaub nrog a puag yog hu ua ib tug neutralization tshuaj tiv thaiv . Cov khoom ntawm no tshuaj tiv thaiv yog ntsev thiab dej. Piv txwv li, lub tshuaj tiv thaiv ntawm hydrochloric kua qaub , HCl, nrog sodium hydroxide, NaOH, cov kev daws teeb meem tsim cov tshuaj sodium chloride, NaCl, thiab qee cov dej molecules ntxiv.
Tsis tas li ntawd, cov tshuaj tiv thaiv ntawm cov kua qaub thiab lub hauv paus hu ua dab tsi?
Ib kua qaub - puag cov tshuaj tiv thaiv yog hu ua ib “neutralization tshuaj tiv thaiv ” Nws muaj kev hloov pauv ntawm hydroxide ion (H +) los ntawm kua qaub mus rau puag . Lawv yog li ntawd feem ntau yog tshem tawm cov tshuaj tiv thaiv ,”tab sis kuj tuaj yeem ua ke cov tshuaj tiv thaiv . Cov khoom yog ntsev thiab feem ntau yog dej.
Ib yam li ntawd, vim li cas cov tshuaj tiv thaiv ntawm cov kua qaub thiab lub hauv paus hu ua Neutralisation? Thaum ib acid thiab ib puag ncig react , cov tshuaj tiv thaiv yog hu ua a neutralization cov tshuaj tiv thaiv . Tias yog vim li cas tshuaj tiv thaiv tsim cov khoom nruab nrab. Dej ib txwm yog ib yam khoom, thiab ntsev kuj tsim. Qhov zoo hydrogen ions los ntawm HCl thiab tsis zoo hydroxide ions los ntawm NaOH ua ke los ua dej.
Ib yam li ntawd, cov tshuaj tiv thaiv hu ua dab tsi thaum cov kua qaub reacts nrog lub hauv paus tsim ntsev thiab dej?
Neutralization yog txheej txheem thaum kua qaub thiab bases teb ua form ntsev thiab dej . Hauv ib tshuaj tiv thaiv rau dej , neutralization ua rau ntau dhau ntawm hydrogen lossis hydroxide ions tam sim no hauv cov tshuaj.
Cov tshuaj tiv thaiv dab tsi yog cov tshuaj tiv thaiv acid puag neutralization?
Neutralization. Cov tshuaj tiv thaiv neutralization yog thaum cov kua qaub thiab lub hauv paus react rau daim ntawv dej thiab ntsev thiab koom nrog ua ke ntawm H+ ions thiab OH- ions los tsim dej . Lub neutralization ntawm lub zog acid thiab lub hauv paus muaj zog muaj pH sib npaug rau 7.
Pom zoo:
Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
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
Dab tsi yog thawj cov protein complex koom nrog hauv cov tshuaj tiv thaiv lub teeb?
Nyob rau hauv cov kev tshwm sim no, cov electron yog thawj zaug kis mus rau ib qho protein hu ua ferredoxin (Fd), ces pauv mus rau ib qho enzyme hu ua NADP + pib superscript, ntxiv rau, kawg superscriptreductase
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
