This study proposes a laboratory experiment for undergraduate students based on the comparison of Classical method (Acid-base titration) with Instrumental method (pH metric titration) and response of glass electrode towards dilute solution of acid/base. Current methodology inculcate the students better about the theoretical approach and practical outcomes of pH measurement for a dilute acid/base solution.
