Using a method proposed earlier by the authors, the degrees of dissociation in individual steps (including the "partial" degrees of dissociation in the second steps) and the concentrations of ionized and nonionized forms in dilute (0.1-10 mM) solutions are calculated for eight homologues of oxalic acids, namely, malonic, succinic, glutaric, adipic, pimelic, suberic, azelaic, and sebacic. Simple empirical equations general for this series were proposed for approximate calculating the first and the second degrees of dissociation and the pH in dilute solutions of these acids. © 2010 Pleiades Publishing, Ltd.
