✦ Synopsis

Estimates of the number of water molecules in the total hydration atmospheres or water-struetum+nhanced regions surrounding the alkali-metal cations in aqueous solution based on four ditferent types of data-the concentration dependence of the Arrhenius activation energy of viscous flow,the cationic isotope effect on conduetance,theratioof limitingconductances,and the conductance ratio in D&)-are in agreement. In the ease of Na+ the number of water molecules in its total hydration atmosphere at 5,20 and 50°C is very nearly the same as the average number of water molecules in the Frank-Wen clusters in pure water at these same temperatures.
