A study has been made on the conductometric titrations of mixtures of organic acids in 2-methoxyethanol as solvent and with 0.01 M DPG as standard titrant. Conductometric titration curves are pèresented and discussed for both aliphatic and aromatic mono- and dicarboxylic acids, and para- and meta-substituted benzenseleninic acids in binary, ternary, and quaternary mixtures. The solvent is suitable for the resolution of acid mixtures in some cases where a quantitative determination is impossible in aqueous solutions owing to very close pK values.

Abstract
A study has been made on the conductometric titrations of mixtures of organic acids in 2-methoxyethanol as solvent and with 0.01 M DPG as standard titrant. Conductometric titration curves are pèresented and discussed for both aliphatic and aromatic mono- and dicarboxylic acids, and para- and meta-substituted benzenseleninic acids in binary, ternary, and quaternary mixtures. The solvent is suitable for the resolution of acid mixtures in some cases where a quantitative determination is impossible in aqueous solutions owing to very close pK values.
