Hydrodynamic permeability, thermoosmotic permeability and thermoosmotic pressures of liquid H2O and 2H2O have been measured and heats of transport estimated. Similar measurements have been made for solutions of KCl in H2O and 2H2O using a copper ferrocyanide impregnated membrane. The permeability of 2H2O is approximately 60% ohat of H2O. This is also the case for solution of KCl in 2H2O and H2O. It appears that the difference in permeability arises on account of the difference in the mobility of H+ and 2H+. Isothermal permeability of H2O and 2H2O vapour through porous ceramic has been measured. Thermoosmotic pressure has been measured and heats of transport estimated. The permeability characteristics differ mainly on account of difference in molecular weights.
