Chemical Reactions

I. Purpose – The purpose of this lab was to observe different type of chemical reactions to write and balance chemical equations.

II. Hypothesis: If you mix two chemicals together, then they will change color and/or bubble/fix.

III. Procedure
- Workstation 1:
1. Light the Bunsen Burner
2. Add 5 – 8 mL of HCL to a test tube that’s in the test tube rack 3. Drop a 2 – cm piece of Mg ribbon into the test tube
4. Record Observations
5. Clean Workstation

- Omit workstation 2

- Workstation 3:
1. Light the Bunsen Burner
2. Record your observations
3. Clean your workstation

* WorkStation 4:
1. Add 10 mL of H2O2 to a test tube
2. Add 4-5 drops of MnO2 to a test tube
3. Record Observations
4. Clean your workstation

* Workstation 5:
1. Place a small scoop of NaHCO3 in a test tube
2. Add 5 mL of HC2H3O2 to the same test tube
3. Record Observations
4. Clean workstation

* Workstation 6:
1. Add a small piece of zinc into a test tube
2. Add about 5 mL of CuSO4 to the same test tube
3. Observe the reaction for 2-3 minutes
4. Record Observation
5. Clean workstation

3. Record Observations
4. Clean Workstation

* Workstation 10:
1. Grab an Iron filing with the tongs and put it in the Bunsen burner 2. Record observations
3. Put the waste in the waste beaker
4. Clean workstation

* Workstation 11:
1. Take a tongue depressor stick and dip it in the solution 2. Light a match and burn the tongue depressor that has the solution on it 3. Observe the reaction
4. Clean workstation
