Waa maxay pH?
PH waa qiyaasta dhaqdhaqaaqa ion hydrogen ee xalka.Biyo saafi ah oo ka kooban dheellitir siman oo ah ion hydrogen togan (H +) iyo
tabanions hydroxide (OH -) waxay leeyihiin pH dhexdhexaad ah.
● Xalka ay ku badan tahay ions hydrogen (H +) marka loo eego biyaha saafiga ah waa aashito waxayna leeyihiin pH ka yar 7.
● Xalka ay ku badan tahay ion hydroxide (OH -) marka loo eego biyaha waa aasaas (alkaline) waxayna leeyihiin pH ka weyn 7.
Waa maxay sababta loola socdo pH-ga biyaha?
