PH yog ib qho kev ntsuas ntawm cov hydrogen ion ua haujlwm hauv cov kua. Cov dej ntshiab uas muaj cov hydrogen ions zoo (H +) thiab cov hydroxide ions tsis zoo (OH -) sib npaug zos muaj pH nruab nrab.
● Cov kua uas muaj cov hydrogen ions (H+) ntau dua li dej ntshiab yog cov kua qaub thiab muaj pH tsawg dua 7.
● Cov kua uas muaj cov hydroxide ions (OH -) ntau dua li dej yog cov basic (alkaline) thiab muaj pH ntau dua 7.
Kev ntsuas PH yog ib kauj ruam tseem ceeb hauv ntau txoj kev kuaj dej thiab cov txheej txheem ntxuav:
● Kev hloov pauv ntawm qib pH ntawm dej tuaj yeem hloov pauv tus cwj pwm ntawm cov tshuaj lom neeg hauv dej.
● PH cuam tshuam rau qhov zoo ntawm cov khoom thiab kev nyab xeeb ntawm cov neeg siv khoom. Kev hloov pauv ntawm pH tuaj yeem hloov pauv qhov saj, xim, lub sijhawm khaws cia, kev ruaj khov ntawm cov khoom thiab acidity.
● Cov pH tsis txaus ntawm cov dej kais tuaj yeem ua rau xeb hauv lub kaw lus faib khoom thiab tuaj yeem ua rau cov hlau hnyav phem tawm mus.
● Kev tswj cov dej pH hauv kev lag luam pab tiv thaiv kev xeb thiab kev puas tsuaj rau cov khoom siv.
● Hauv cov chaw ib puag ncig ntuj, pH tuaj yeem cuam tshuam rau cov nroj tsuag thiab tsiaj txhu.
