Dempsey (eds.), Ionization … Weba more stable conjugate base forms more easily. give up a proton more easily if it gives rise to a stable conjugate base. Many organic compounds contain hydroxyl or OH groups, some of which are acidic and some of which are not. Three kinds of compounds containing this group are alcohols, phenols and carboxylic acids. Examples of
WebJul 20, 2024 · pKa(HA) + pKb(A −) = pKw. Thus the product of the acid constant for a weak acid and the base constant for the conjugate base must be Kw, and the sum of p Ka and p Kb for a conjugate acid-base pair is 14. Equation 14.7.4 or 14.7.8 enables us to calculate the base constant of a conjugate base from the acid constant of the acid, and vice versa.
