pH and pOH - everything you need to know! ???? Now that you know everything about the autoionization of water and the ionic product of water - Kw - we can study the hydrogen potential (pH) and the hydroxyl potential (pOH). In this chemical equilibrium video lesson, we will see that pH is a useful way to indicate whether a medium is acidic, basic or neutral. It is important to note that pH and pPH do not indicate whether one acid or base is stronger than another; what does this, that is, indicates the strength of acids, is the acidity constant (Ka). In this chemical equilibrium video lesson, we will do several examples of pH and pOH calculations using the concepts of Kw (water autoionization constant) and Ka (acidity constant) studied in the previous chemical equilibrium video lessons.
