Description
Summary:The feasibility of electrolytic conductivity is performed using two-electrode system. A precision LCR meter is utilized to measure the ac resistance of electrolytic solution which is traceable to reference standard of impedance at CSIR-National Physical Laboratory. KCl solutions with different molality are used to establish the measurement system. The measurement of ac resistance is performed at frequencies above 10 kHz to minimize the impact of electrode polarization. Initially, the measurement setup was validated using a certified reference material. The KCl solutions with different molality are prepared gravimetrically. Thereafter, electrolytic conductivity of the aqueous solutions is computed for different molality of KCl solutions. The preliminary measurement suggested that the two-electrode system may be utilized for the measurement of electrolytic conductivity from 0.005 to 0.1 M upto 1 MHz.
