THE VARIATION OF SPECIFIC CONDUCTIVITY WITH CONCENTRATION OF WEAK ELECTROLYTES IN NON-AQUEOUS SOLVENTS

The variations of specific conductivity of weak electrolytes with concentration has been studied in non-aqueous solvents, It has bean observed that the solutions can be divided into two categories: (i) The solutions which give a straight line plot or nearly so for µ - c within the concentration range studied here. (ii) The plot of µ - c shows a maximum. In come cases the first concentration of the solute is so high that further addition of the solute diminishes the conductivity. It has been suggested that if the relative increase in the viscosity is more than the relative increase in the specific conductivity with increasing concentration then a maximum is obtained in the plot of µ - c
