Ionized phenol

WebHA = A- + H+ and Ka = [A-]* [H+] / [HA] This is the definition in common usage. For many practical purposes it is more convenient to discuss the logarithmic constant, pKa. pKa = -log10 Ka. The larger the value of pKa, the smaller the extent of dissociation at any given pH - that is, the weaker the acid. Web21 jan. 2011 · Dr. Sandle is a pharmaceutical microbiologist.
