PH yog ib qho kev ntsuas ntawm hydrogen ion kev ua hauv kev daws teeb meem.Cov dej ntshiab uas muaj qhov sib npaug ntawm qhov zoo hydrogen ions (H +) thiab tsis zoo hydroxide ions (OH -) muaj qhov nruab nrab pH.
● Cov kev daws teeb meem nrog cov ntsiab lus siab ntawm hydrogen ions (H +) dua li cov dej ntshiab yog acidic thiab muaj pH tsawg dua 7.
● Cov kev daws teeb meem nrog cov ntsiab lus siab ntawm hydroxide ions (OH -) dua li dej yog qhov yooj yim (alkaline) thiab muaj pH ntau dua 7.
Kev ntsuas PH yog ib kauj ruam tseem ceeb hauv ntau qhov kev sim dej thiab kev ua kom huv:
● Kev hloov pauv ntawm pH ntawm cov dej tuaj yeem hloov cov cwj pwm ntawm cov tshuaj hauv dej.
● PH cuam tshuam cov khoom zoo thiab kev nyab xeeb ntawm cov neeg siv khoom.Kev hloov pauv hauv pH tuaj yeem hloov qhov tsw, xim, txee lub neej, khoom ruaj khov thiab acidity.
● Kev tsis txaus pH ntawm cov dej kais dej tuaj yeem ua rau xeb hauv cov kab ke faib khoom thiab tuaj yeem tso cov hlau hnyav hnyav tuaj yeem tawm.
● Tswj cov dej pH ib puag ncig pab tiv thaiv corrosion thiab puas rau cov khoom siv.
● Hauv ib puag ncig ntuj, pH tuaj yeem cuam tshuam rau cov nroj tsuag thiab tsiaj txhu.
