pH yog dab tsi?
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 zoohydroxide ions (OH -) muaj pH nruab nrab.
● 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.
Vim li cas thiaj saib xyuas pH ntawm dej?
