Kodi pH ndi chiyani?
PH ndi muyeso wa hydrogen ion zochita mu yankho.Madzi oyera omwe ali ndi muyezo wofanana wa ayoni wa hydrogen (H +) ndi
zoipahydroxide ions (OH -) ali ndi pH yopanda ndale.
● Zothetsera zokhala ndi ma hydrogen ion (H +) ochulukirachulukira kuposa madzi amchere zimakhala acidic ndipo zimakhala ndi pH yosakwana 7.
● Njira zothanirana ndi ma hydroxide (OH -) zochulukira kwambiri kuposa madzi ndizoyambira (zamchere) ndipo zimakhala ndi pH yopitilira 7.
