title: Graphic determination of equivalence volumes in potentiometric titrations of mixtures of weak acids-I Two monobasic acids.
abstract: A titration method for analysis of binary mixtures of weak acids is given. The equivalence volumes of the individual acids can be determined graphically from only two titration points. However, use of more than two points gives a more accurate result. Mixtures of acetic acid with ascorbic acid, hydroxyacetic and monochloroacetic (Delta log K(H)(HA), = 0.5-1.9) are titrated with an error of approximately, 0.5-2.5% in all three cases.
