Importance of potentiometry
WitrynaThe potentiometric titration was conducted once at each level. Calibration curve was drawn by plotting test sample weight in gram on x axis and titre values on y axis. The values of correlation coefficient, slope and intercept are given in table 3. And graph is given in fig no. 1 Table No. 3 : Regression values Correlation Coefficient 0.9999 Witryna2 lip 2024 · What is the importance of potentiometry? In potentiometry we measure the potential of an electrochemical cell under static conditions. Because no current—or only a negligible current—flows through the electrochemical cell, its composition remains unchanged. For this reason, potentiometry is a useful quantitative method.
