  1. NORTHBROOK

  2. Task Identify the solutions in 12 pipettes from the given list • 0.2M Potassium chromate  • 1.0M Aluminum chloride • 1.0M Potassium carbonate • 6M Hydrochloric acid • 6M Sodium hydroxide • 0.1M Silver nitrate • 6M Ammonia • 0.1M Lead (II) nitrate • 0.1M Iron (III) nitrate • 1.0M Sodium acetate • 0.1M Copper (II) sulfate • 0.1M Nickel (II) chloride

  3. Pre-Lab -all general equations and net ionic equations written out -safety information for reactants and precipitates gathered -color of pipettes observed -pH of solutions taken

  4. Procedure add pix from the procedure on the next few slides

  5. Precipitate K2CO3(aq) + 2NaOH(aq) --> 2KOH(aq) + Na2CO3(s)

  6. No Precipitate 2AgNO3(aq) + CuSO4(aq) --> Ag2SO4(aq) +Cu(NO3)2(aq)

  7. Precipitate K2CO3(aq) + 2NaOH(aq) --> 2KOH(aq) + Na2CO3(s)

  8. No Precipitate 2AgNO3(aq) + CuSO4(aq) --> Ag2SO4(aq) +Cu(NO3)2(aq)

  9. Error Analysis

  10. Conclusion Pipette 1: Hydrochloric acid Pipette 2: Silver nitrate Pipette 3: Potassium carbonate Pipette 4: Iron (III) nitrate Pipette 5: Copper (II) sulfate Pipette 6: Aluminum chloride Pipette 7: Lead (II) nitrate  Pipette 8: Nickel (II) chloride Pipette 9: Sodium acetate Pipette 10: Ammonia Pipette 11: Sodium hydroxide Pipette 12: Potassium chromate
