Abstract
Prior to measuring the concentration of a nonelectrolyte in an electrolyte solution, the electric conductivity of a mixed solution containing electrolytes and the nonelectrolyte is previously measured so as to determine the correlation between the electric conductivity and the concentration of the nonelectrolyte as to the same system. The concentration of the nonelectrolyte in the mixed solution can be determined from the electric conductivity obtained by measuring the mixed solution, based on the correlation.
