Electrometric titration curves of dibasic acids, Part IV. Corrections for interionic effects and for solvent electrostriction. First and second dissociation constants of some n-paraffin alpha omega-dicarboxylic acids, alkyl- and dialkyl-malonic acids, s-di- and -tetra-alkylsuccinic acids, beta-alkyl- and beta beta-dialkyl-glutaric acids, and cyclic 1 : 1-diacetic acids. Remarks on the configurations and molecular dimensions of these acids in dilute aqueous solution.
