Abstract

Calculations have been made of the conditions that are necessary for the existence of vertical equivalence point inflexions in the titration curves of dibasic, tribasic, and polybasic acids. Account has been taken of the effects of finite acid concentration, of finite concentration of the titrating base, of finite strength of the titrating base, and of activity coefficients. As a rule, each of these effects causes a flattening of the titration curves and the ultimate disappearance of inflexions.
