Lab description and primary aims of the lab: 

Our objective is to study the variation of cell potential of Zn│Zn2+ ││Cu2+│Cu cell with change in the concentration of electrolytes (CuSO4 and ZnSO4) at room temperature. Students understand the terms, electrochemical cell, electrolytic cell, Daniell cell, salt bridge, EMF. Students acquire the skill to construct a Daniell cell. Students understand the significance of salt bridge. Students acquire the skill to calculate the electrode potential of a half cell and full cell using the Nernst equation. Students acquire the skill to measure the EMF of a cell by viewing animation & simulator. Students understand how the electrode potential of a given cell varies with the concentration of electrolytes in the anodic and cathodic half cell.
