Measurement of Conductivity of an Aqueous Solution and nature of combined Materials, Electrodes

The present work aims to determine the influence of the nature of the combined materials on the measurement of the conductivity of an aqueous ionic solution. In this study, 4 types of electrodes (iron (Fe), copper (Cu), aluminum (Al) and lead Pb) were used. Correlation curves, current intensities and the degree of mineralization of the solution were layout. The correlation coefficients varying between 0.9877 and 1 indicate a very good correlation between the degree of mineralization of the ionic solution and the intensity of the measured direct current and the reliability of the method. The results show that for the same solution, the current intensity is a function of the nature of the two combined electrodes.
