Membrane Potentials across the Cation Exchange Membrane in Aqueous Mixed Electrolyte Solutions

Article Preview

Abstract:

Membrane Potentials across the Cation Exchange Membrane in Aqueous Mixed Solutions Made of Two Kinds of Electrolytes Were Experimentally Studied. Effects of both the Concentration and the Species of Electrolytes on Membrane Potentials Were Presented. for any Mixed Solution Made of Two Kinds of Electrolytes, when the Total Electrolyte Concentration at Right Side of the Membrane Is Fixed, the Membrane Potential Increases with the Total Electrolyte Concentration at Left Side of the Membrane. however, such Increase Is Rather Slight at both Low and High Concentrations. when the Concentrations at each Side of the Membrane Are Equivalent for Three Mixed Solution Systems, the Membrane Potential Decreases with such Order: ΦKCl+NaCl>ΦKCl+MgCl2>ΦKCl+AlCl3.
