Activity 3
Single Displacement Reactions
Mg + CuSO
3 ---> MgSO
3 + Cu
magnesium + copper sulfate ---> magnesium sulfate + copper
Materials
needed for each station:
- 1 magnesium ribbon (2 cm)
- 1 test tube rack
- 1 pipet (dropper)
- 1 flame source
- 1 ring stand or burner stand
- 1 test tube clamp
- 1 medium test tube
- 1 test tube stopper
- 2 mL copper sulfate solution
|
Procedures:
- Pipet 2 mL copper sulfate solution into a medium test tube.
Observe the color of the solution. Record your observations into
your lab book.
- Place a 2 cm strip of magnesium ribbon into the copper sulfate
solution. Securely close the tube with a rubber stopper and
gently shake the test tube.
- Place the tube in the rack, remove the stopper, and, over the
next few minutes, observe what is occuring. Record your
observations into your lab book.
- Continue to note changes and observe the reaction. Answer
the Results questions for Lab Activity 3.
