Experiment 21: Electrochemical Cells and Electroplating for AP Chemistry
For a quick review on stoichiometry, refer to the following concepts:
- Redox Reactions for AP Chemistry
- Electrochemical Cells for AP Chemistry
- Quantitative Aspects of Electrochemistry for AP Chemistry
- Nernst Equation for AP Chemistry
Electrochemical cells are constructed, and their cell potentials are determined with a voltmeter. Electroplating is accomplished by using an external power supply, usually a battery, to plate a metal onto an electrode. (See Electrochemistry chapter.)
- filter crucibles and adapters
- filter flasks
- power supply (battery)
- test tube(s)
The cell potentials are measured with a voltmeter. Refer to the figure of the electrochemical cell in Chapter 16.
Normally, no calculations are required.
Cells may vary in composition or concentrations.
