Electrochemistry ELECTROCHEMICAL CELLS 3-21-05 Purpose: In this experimentation, several different half- cadreular phones forget be prepared and connected to find the voltages generated. Also, the submergence impart be change in one of the solutions to bring out how this affects the cell potential drop. Thirdly, the electrical potential of a cell containing silver grey 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 constitution constant of the tetraamminecopper (II) complex ion. This experiment uses a microscale technique. Procedure: 1.
adopt materials and put on look for eye protection. 2. Prepare a test cell to measure the voltage of the copper and surface 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.
