This lab uses aluminum foil and a copper (II) sulfate solution to demonstrate oxidation-reduction reactions. Students also use the NYS Reference Table - Table J (Activity Series) to help them predict which metals would be able to replace other metal ions in a compound.
The aluminum, being more active than the copper (II) ions, replaces the ions in the sulfate compound. The copper (II) ions then "plate" onto the remaining aluminum or fall to the bottom of the reaction container, often creating interesting stalactite-like patterns.
My labs are straightforward. Some of them are paper labs, but the ones that involve significant laboratory setup or calculations to be made on the part of the teacher are written about in a Teacher Notes section at the end of those particular labs. I use relatively safe and inexpensive chemicals. Of course, safety precautions are always noted at the beginning of the lab.
