CCXCIV.—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 αω-dicarboxylic acids, alkyl- and dialkyl-malonic acids, s-di- and -tetra-alkylsuccinic acids, β-alkyl-and ββ-dialkyl-glutaric acids, and cyclic 1 : 1-di-acetic acids. Remarks on the configurations and molecular dimensions of these acids in dilute aqueous solution
