pH ke eng?
PH ke tekanyo ea tšebetso ea hydrogen ion ka tharollo. Metsi a hloekileng a nang le tekanyo e lekanang ea li-ion tsa hydrogen (H +) le
mpehydroxide ions (OH -) e na le pH e sa nke lehlakore.
● Litharollo tse nang le li-ion tsa haedrojene tse ngata (H +) ho feta metsi a hloekileng li na le asiti 'me li na le pH e ka tlase ho 7.
● Litharollo tse nang le li-ion tsa hydroxide tse ngata (OH -) ho feta metsi ke tsa motheo (alkaline) 'me li na le pH e kholo ho feta 7.
