Diffusion of solvent in membrane electrodes

Summary

The generation of a potential difference is caused, according toScatchard (12), by the transport of matter — electrolyte as well as non-electrolyte — through the membrane. Clay membranes are found to sorb water vapour and swell — the amount of each being indeed very small. The diffusion coefficient of water is found to be of the order of 10−7 cm2/sec. Na-form of membrane which swells more allows greater diffusion than the Ca-form which swells less. Again, presence of free oxides in membranes reduces swelling as well as diffusion.
