Today you will react solid aluminum metal with a solution of copper (II) chloride.
Answer the following questions.
1.
2.
3.
4.
5.
6.
What does the aluminum look like?
Initially what does the copper (II) chloride look like?
What will need to be done to the copper (II) chloride?
What safety concerns might you have?
What safety equipment is required for this reaction?
What data might you collect during this reaction?
Procedures:
1.
Pour 25 ml of water into the graduated. Record the temperature of the water.
2.
Measure out a small amount of Copper Chloride into a plastic cup. Record the mass of
Copper Chloride.
3.
Add the 25mL of water to the flask. Add the Copper Chloride and swirl gently till all
crystals are dissolved. Record observations and take another temperature reading.
4.
Measure out about 1 gram of aluminum foil and record the mass.
5.
Lightly crumple and tear the foil into small pieces and place it into the copper chloride
solution. Wait about 5 minutes making observations during this time. Record all evidence
of a chemical reaction. You may stir the mixture during this time.
6.
Lightly touch the side of the flask and record any change it touch and temperature.
7.
After the reaction has stopped, carefully separate the Aluminum Chloride solution from the
newly formed Copper by pouring the Aluminum Chloride down the sink while using the
scoop to prevent any solids from escaping.
8.
Record the appearance of the solid that remains.
9.
Dispose of the solid in the trash and clean up your lab area and return all materials.
Observations
Post Lab Questions:
1.
Are the final products the same as the initial reactants?
How do you know?
2.
This reaction represents a chemical change. Give at least three markers to prove a chemical
change occurred.
3.
Hypothesize what occurred in this reaction. Use the names and/or formulas for the
elements and compounds.
