The dissociation constants of dibasic carboxylic acids [HOOC(CH2)nCOOH, n = 0~4] in methanol, N,N-dimethylformamide and acetonitrile have been determined by the potentiometric method with a glass electrode. The difference between over-all dissociation constants in each other solvent is found to be of the same order of magnitude, and the K1/K2 ratios in aprotic dimethylformamide and acetonitrile are much greater than those in protic methanol and water.
