Tracer-diffusion coefficients of water in aqueous tetra-alkylammonium chloride solutions
Abstract
The tracer-diffusion coefficients of water in aqueous solutions of tetramethylammonium chloride, tetraethylammonium chloride and tetra-n-propylammonium chloride have been determined at 298.2 K by the diaphragm-cell method using deuterium as a tracer. Observed retardation of water diffusion is discussed in terms of the obstruction effect by applying Wang's theory.
