Today in class, you will complete a simple chemical reaction. You will measure out 0.25g of aluminum foil and combine that with 5.0mL of aqueous copper (II) chloride. Once you put the foil in the solution, allow the reaction to go for 10 minutes or until the bubbles stop forming, whichever comes first. While waiting, do the following:
1. Predict the products and write the balanced chemical equation.
2. Convert the given amounts into moles using the molar mass.
3. We will predict how much product you should obtain.
After 10 minutes, filter the solution into a graduated cylinder. What is the brown substance left on the filter paper? What is the liquid in the cylinder? Deduct the mass of the filter paper from the brown solid (1.5g).
Take the mass of the brown solid and record the volume of the remaining liquid. Did you get the amounts you were supposed to get? Why or why not?
Run the experiment for a second time. Did you get better results? You should.
