Conjugate Acids and Bases. When an acid loses an H+ ion it becomes a conjugate base. For example, hydrochloric acid (HCl) loses an H+ ion to become its conjugate base Cl-1. The conjugate base of water, H2O, is the hydroxide ion, OH-1. Likewise, when a base gains an H+ ion, it becomes its conjugate …

The conjugate base, A-1, undergoes hydrolysis by the reaction: A-1 (aq) + H2O (l) ( HA (aq) + OH-1 (aq) This gives an equivalence point in the basic region (pH>7). The equilibrium for this reaction is described by the Kb for the conjugate base: The [A-1] is calculated from the intial moles of HA and the total volume of the reaction mixture at ...
