The main purpose of this experiment is to construct voltaic cells, gauge the corresponding cell potentials and compare the calculated cell potentials with the theoretical cell potentials. The experiment is also designed to discover the properties of electrochemical cells. A voltaic cell is a system that is specially prepared where oxidation-reduction (redox) reaction occurs impulsively. The oxidation reaction occurs in the anode half-cell while reduction reaction occurs in the cathode half-cell. The oxidation and reduction reactions are separated to enable current run through an external wire producing an easily gauged electrical potential. The electrical potential is predicted by use of standard reduction potentials and also can be calculated combining the potentials of half reactions. The half-reaction which is more negative is oxidation hence the reduction reaction is one that is tabulated. The reduction potentials are gauged at standard conditions; I atmosphere, 25 degree Celsius and IM concentration of solutions. [Show More]
