Abstract

The diffusion of cupric sulfate into water has been studied by measuring the concentration at different distances and at successive times as the diffusion progressed. The cupric sulfate was allowed to diffuse upward from a solution of constant concentration into a thin flat cell of optical glass filled with pure water. The concentration at different distances from the open end of the cell, was determined by measuring the absorption of monochromatic red light. The diffusion coefficient has been calculated by using a method similar to Zuber's for the integration of the general form of the equation for linear diffusion in which the diffusion coefficient is a function of concentration.
