Experiment 20: An Electrochemical Series for AP Chemistry
For a quick review on stoichiometry, refer to the following concepts:
- General Aspects of Chemical Reactions and Equations for AP Chemistry
- General Properties of Aqueous Solutions for AP Chemistry
- Precipitation Reactions for AP Chemistry
- Oxidation–Reduction Reactions for AP Chemistry
- Coordination Compounds for AP Chemistry
- Acid–Base Reactions for AP Chemistry
The reactivity of several metals with solutions containing ions of other metals is observed. This experiment involves the development of an activity series. (See the Reactions and Periodicity chapter.)
- graduated cylinder
- test tube(s)
- test tube rack
This experiment is based on observations, not measurements.
Observations, not calculations, are needed.
The more active metal will displace a less active metal from a solution.
Hydrogen is usually included in the series by using acids.
