229for silver sulfate and silver acetate (Table VI) is positive and passes through a maximum at X,,, = 0.45 with LX = 5.8 and 5.1, respectively. Thus an increase of 3.0 and 3.7 moles of AN occurs in the case of dioxane + AN mixtures for silver sulfate and silver acetate and an increase of 5.8 and 5.1 moles of Me,SO occurs in the case of dioxane + Me,SO for silver sulfate and silver acetate, respectively, per faraday, relative to the mean molar velocity of the solvent mixtures as reference (23) in the cathode compartment when the solutions of these salts are electrolyzed at the given composition of the solvent mixtures. The enrichment of AN or Me,SO in the cathode compartment arises largely through their transport by the silver ion while the anion transports dioxane in the opposite directlon, i.e., toward the anode. These two effects add together and thus a heteroselective solvation results in large A values. These results support the conclusions based on the transfer energy variation of the ions observed earlier.Henry's constants for phenol over its aqueous solutlon were measured In the temperature range from -2 to 27 OC. An equation was proposed to correlate these data and those estimated from the lllerature data at 44-90 OC.
