Choose the false statement. O The pH of the acetic acid solution at the equivalence point is less than 7.00 O In contrast to strong acids and bases, the shape of the titration curve for a weak acid or a weak base depends on the identity of the acid or the base and the corresponding Ka or Kb. The end point of titration is the point at which the number of moles of base (or acid) added equals the number of moles of acid (or base) originally present in the solution. O The shape of the curve for a titration involving a strong acid and a strong base depends on only the concentrations of the acid and base, not their identities.
