Utilization of Used-Up Consumer Product Dry Cell for Developing New Experiment

  Sudesh Bhaskar Ghoderao

As an alternative to the regular experiments dealing with analysis of an ore, an experiment is developed based on titrimetric analysis of some used-up consumer product. The determination of manganese from the electrolyte powder in a run-down dry cell by Volhard's method is an alternative for analysis of pyrolusite ore. The student may later think about the relationship between the properties and composition of the material also. The experiment may be successfully incorporated in the practical course for undergraduate students of Analytical and Inorganic Chemistry. The results of present work indicate the importance of composition with reference to amounts of manganese (IV) oxide, graphite, ammonium chloride (and zinc chloride) where MnO2, seems to be the major constituent of the dry cell.
