The bi-ionic potential (BIP) values across the parchment supported cupric phosphate and Iron Phosphate membrane with various combination of 1:1 electrolytes at different concentrations have been measured theoretical values of BIP have been calculated using the BIP theories developed recently by Toyoshima et al based on principles of non equilibrium thermo dynamics comparison of experimental and theoretical BIP values shows that theoretical equations of BIP are applicable to the parchment supported membrane. Membrane conductivity in contact with a single electrolyte has been experimentally determined to evaluate the selectivity of the membrane using the predetermined values of intra membrane mobility ratio. The selectivity sequence of the membrane is found to be. K+> Na+> Li+.
