... Like Ka, pKa is a constant. Looking at this relationship you can see that when the ratio [A]/[HA] = 1.0, log of 1.0 = 0, and pH = pKa. Thus one way to think of pKa is that the value is equal to the pH at which 50% of an acid or base will be protonated and 50% will not. A pH of approximately 2.2 is ...
