Excess Absorption

A method of obtaining relative and absolute rate constants for proton transfer equilibria is described. It is suitable for equilibria of the type[Formula: see text]in dilute (< 0.1 M) solutions of medium strong inorganic acids. To obtain absolute values of kd, kr it is necessary to know the value of ΔV0 for the equilibrium. Ultrasonic absorption data for aqueous solutions of H3PO4, H3AsO4, and H2SO4 at 20, 10, and 0 °C are presented together with data at 20 °C for H3PO3, H2SeO3, HIO4, NaHSO4, KHSO4, and NH4HSO4. From analysis of the concentration dependence of the excess absorption, values of Ka are calculated for these acids, and values of kd, kr for those where ΔV0 is available. The Ka obtained are in reasonable agreement with literature values except for HIO4 and H2SeO4. The absolute values of kr for H3PO4, H3AsO4, and HSO4− indicate that the diffusion controlled recombination process postulated is complete when the ions are about 15 Å from each other.

Acids And Bases

Colloidal electrolytes are solutions of salts in which one ion has been replaced by a heavily hydrated polyvalent micelle, carrying an equivalent sum total of electrical charges and also serving as an excellent conductor of electricity. This is the conclusion to which our investigations have led us. It will probably prove that this new class includes, under certain conditions, most organic compounds containing more than eight carbon atoms, and capable of forming ions, also solutions of the acid and alkali proteins, dyes, indicators, sulphonates, soaps, and possibly even of such compounds as chromium chloride, and of the alkaline tungstates, zincates, tellurates, and silicates. Many non-aqueous solutions may also be included in the same category, as will be shown in a later communication, and it is indeed probable that the class includes as many members as the acids and bases together.
