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 * Workstation 7: 1. Combine 5-8 drops of AgNO3 and CaCl2 in a test tube 2. Observe reaction for 2-3 minutes 3. Record Observations 4. Clean Workstation * Workstation 8: . Combine 4-5 drops of CaCl2 and NaPO4 in a test tube 2. Observe reaction for 1 minute 3. Record Observations 4. Clean Workstation * Workstation 9: 1. Combine 4-5 drops of NA2SO4 and Pb(C2H3O2)2 in a test tube 2. Observe reaction for 1 minute 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 IV. Data: 1. Chemicals Used| Hydrochloric acid and Magnesium| Observations| Fizzes| Type of Reaction| Single| Equation| HCl + Mg -> MgCl2 + H2| 3 Chemicals Used| Hydro carbonic acid and oxygen| Observations| Light roaring, blue flame| Type of Reaction| Combustion| Equation| CH4 + O2 -> C2O + H2| 4. Chemicals Used| Hydrogen and Oxygen| Observations| It diffuses, foggy| Type of Reaction| Combustion| Equation| H2O2 -> H2O + O2| 5. Chemicals Used| Hydrocarbonic hydroxide acid and Sodium Carbonic Acid| Observations| Bubbles all the way out of the test tube|
Type of Reaction| Double| Equation| HC2H3O2 + NaHCO3 -> | 6. Chemicals Used| Zinc and Copper Sulfate | Observations| Turns black and dissinagrates| Type of Reaction| Single| Equation| Zn + CuSO4 -> ZnSO4 + Cu| 7. Chemicals Used| Aluminum nitrate and calcium chloride| Observations| White and chunky | Type of Reaction| Double| Equation| Al(NO4)3 + CaCl2 -> Ca(NO4)2 + AgCl3| 8. Chemicals Used| Calcium chloride and Sodium Phosphate| Observations| Very cloudy| Type of Reaction| Double| Equation| CaCl2 + NaPO4 -> NaCl + Ca3(PO4)2| 9. Chemicals Used| Sodium sulfate and lead acetate| Observations| Very cloudy and foggy|
Type of Reaction| Double| Equation| Na2SO4 + Pb(C2H3O2)2 -> Na(C2H3O2) + PbSO4| 10. Chemicals Used| Iron and Oxygen| Observations| Sparks; turns orange in fire| Type of Reaction| Combustion | Equation| Fe + O2 -> Fe2O| 11. Chemicals Used| Carbon hydroxide and oxygen| Observations| Caught on fire due to oxygen| Type of Reaction| Combustion| Equation| C3H8O + O2 -> C2O3 + OH| V. Difficulties – One difficulty is that dust could’ve gotten in the chemicals. Also the test tubes could still have some substances in it. Another difficulty is you could’ve put too much liquid or not enough in the different mixtures. VI.
Calculations – No calculations for this lab VII. Conclusion: 1. Potassium bromate is heated; it decomposes into potassium bromide and a gas. KBrO3 + heat -> KBr + (g) 2. Sodium metal reacts violently with water to produce hydroxide and a gas. Na2(m) + H2O = (NaOH) + (g) The purpose of this lab was to observe different types of chemical reactions and we did that at eleven different stations. My hypothesis was correct because in every chemical reaction I performed there was a color change or it bubbled/ fizzed. I learned that chemical reactions come in numerous ways. I also learn that some chemicals need certain properties to keep in going.
