Experiment 8: Molecules and Reactions “Foiled Again”
Introduction:
When it come to a chemical reaction between elements and molecules to form a compound, there
are two primary factors that come to play. One, the ratio of one reactant to another reactant. Two,
the number of atoms per mole of each reactant. These factors are commonly referred as
Stoichiometry. In this lab, we will react different masses of aluminum with different volumes of
copper (II) sulfate solution. After completed, the product will be washed, dried, and weighed for
more data to be collected. With these data, we can draw conclusions about the stoichiometry of
the lab experiment.
Materials:
1. Two 150 mL beakers
2. Grease pencil
3. Graduated cylinder
4. 0.250M copper (II) sulfate solution
5. 6M HCl
6. Aluminum foil
7. 25 mL water
8. 25 mL ethanol
, 9. Heating plate
10. Lab manual
11. Lab notebook
Observations and Experimental Data:
Part A: Chemistry of Aluminum and Copper (II) Sulfate
This is the data table of Part A, where student is needed to calculate the mole of the Al and Cu as
well the ratio of Cu mol/Al mol and the percentage yield.
