Electrochemistry ELECTROCHEMICAL CELLS 3-21-05 Purpose: In this look into, several opposite half- mobile phones go away be prepared and committed to find the voltages generated. Also, the concentration exit be change in one of the solutions to see how this affects the cell potential. Thirdly, the electrical potential of a cell containing argent and silver chloride will be surveyd. Lastly, a cell containing cop (II) and ammonium hydroxide will be constructed. The potential and the Nernst equation will be used to reckon the formation constant of the tetraamminecopper (II) complex ion. This experiment uses a microscale technique. social occasion: 1.
Collect materials and put on look for eye protection. 2. urinate a test cell to measure the voltage of the copper and zinc half-cells. 3. Put around 2 mL 1.0 M zinc nitrate solution in one of the cracker bonbon wells of a 24-well plate. 4. Put approximately 2 mL of 1.0 M copper (II) nitrate in an adjacent well. polish up small ...If you want to get a full essay, rate it on our website:
