Electrochemistry ELECTROCHEMICAL CELLS 3-21-05 Purpose: In this experimentation, several different half- electric cellular phones forget be prepared and connected to find the voltages generated. Also, the soaking up impart be change in one of the solutions to divulge how this affects the cell effectiveness. Thirdly, the electrical potential of a cell containing smooth-spoken medal and silver chloride will be meterd. Lastly, a cell containing copper (II) and ammonium hydroxide will be constructed. The potential and the Nernst equation will be used to calculate the governance constant of the tetraamminecopper (II) complex ion. This experiment uses a microscale technique. Procedure: 1.
hive away materials and put on look for eye protection. 2. Prepare a test cell to measure the voltage of the copper and zinc half-cells. 3. Put approximately 2 mL 1.0 M zinc nitrate solution in one of the center rise up of a 24-well plate. 4. Put approximately 2 mL of 1.0 M copper (II) nitrate in an adjacent well.
