The experimental rcsults for 2-ethylhexanol and decanol are shown in Figs. 8 and 9. The plots of log D us. log [HCl] for the 2 M acids are reasonably flat as expected, with the small differentiation between HC1-HC104 and HC1-HNO, mixtures due t o the small difference in water activities. With G and 10 M acids, this differentiation would be expected to increase, and it does, but an initial decrease in D characteristic of a small common ion effect also occurs. Apparently a t these higher ionic strengths the lowered water activity increases CYHZ more rapidly than CYHCl, so that instead of CYHCl < OCHZ, the condition ffHC1
