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.
