Abstract

Diffusion coefficients (<i>D</i>) of arsenite and arsenate at various pH, or degrees of dissociation, were reported by diffusion cell, some values of which are newly reported in this letter. Systematic decrease of <i>D</i> depending on the dissociation of arsenite and arsenate shows that <i>D</i> is closely related to the size of the hydrated ions.
