Given the titration curve of a weak acid, at which region is the buffer capacity considered maximized? IV II pH volume of OH- added Select one: O a. Region I, because there is no strong base added O b. Region II, because there is almost equal amounts of weak acid and conjugate base O c. Region III, because it is the equivalence point, where equal amount of base is added to the weak acid O d. Region IV, because the buffer can easily neutralize acid or base at this point
