Inflection point, slope, and equivalence point in a titration My textbook, Harris 7th Edition Quantitative Chemical Analysis, says:


  In titrations involving 1:1 stoichiometry of reactants, the equivalence point is the steepest point of the titration curve. This is true of acid-base, complexometric, and redox titrations as well.


My question is, does this apply to all acid-base titrations (strong-strong and weak-strong)? My intuition seems to say that it only applies to strong-strong, but I may be incorrect.
Your intuition is not sufficient in this matter. The equivalence point is the steepest point of any titration curve, however weak or strong is the acid and the base.
