    • Class Data:
    • Discussion/Post-lab question clarifications
      • Question #1
        • Reference CLASS DATA.
        • It is difficult to say if we have reached equilibrium based on the data we have collected as a class. As part of your explanation, discuss what additional steps we would need to take to answer this appropriately.
      • Question #2
        • Consider something that we could do to our reaction mixture other than addiing more catalyst.
  • Experiment #5: Determination of Keq by spectrophotometry
  • Experiment #8: Buffer Solutions
    • Lab Handout
      • For parts 1&2, we will perform the alternate study assignment
      • System 3 Prelab Requirements:
        • PURPOSE & Buffer System REACTION

I will be updating some of the laboratory activities this semester. The handouts below are for reference only. The files above are ready to print.


 

  • Experiment #12: Reactivity Series & Galvanic Cells (2011)
    • Lab Handout
    • Prelab:
      • Please provide a standard prelab, including preparation of data table in the lab notebook.
        • Note: Reactions need not be included as part of the prelab.
    • Mini-Report:
      • Provide calculations, equations, results, and diagrams for each part of the lab as indicated in the lab handout.
      • A formal discussion and conclusions are NOT required.
  • Experiment #13: Galvanic Cells & the Nernst Equation
    • Lab Handout
    • Mini-Report:
      • Provide calculations, equations, results, graphs and diagrams for each part of the lab as indicated in the lab handout.
      • A formal discussion and conclusions are NOT required.
  • Experiment #14: Electrolytic Cells & the determination of the Faraday Constant.
    • Lab Handout
    • Mini-Report:
      • Provide calculations, equations, results, and diagrams for each part of the lab as indicated in the lab handout.
      • A formal discussion and conclusions are NOT required.

 

SAMPLE LAB TESTS & TEST REVIEW

  • Experiment #2 Practice:
    • Rework exam Prelab Question #1
    • Rework your own data analysis, starting from your time data for trials 1-6 and trials 7-12.
      • Both orders you determine should be 1.
  • Experiment 4 - Student Data (previous semester)
    • I recommend determining Q for the reaction for Week 4 for both Esterification and Hydrolysis as extra practice for Lab Test #1.
    • Answer Key (for Week 4)
