Laboratory Manual Handouts, Reading & Additional Information

  • SKIP for Spring 2018: Experiment #1: Factors Affecting Reaction Rates
  • Experiment #6: LeChatelier's Principle (revised Spring 2018)
    • Lab Handout - Though some minor changes may still be made,
      this file is ready to print
      .
  • Experiment #8: Buffer Solutions
    • Lab Handout (Revised Spring 2017)
      • For Parts 1&2, we will perform the alternate study assignment.
        • No Prelab required for Parts 1& 2
      • Part 3 Prelab Requirements:
        • PURPOSE & Buffer System REACTION
        • DATA TABLE
      • Mini Lab Report:
        • Follow the guidelines. However, you may omit Parts 1-2 for the report.
          We only performed Part 3 as an experiment.
        • Be sure to plot moles (or mmol) acid & base vs. pH.
        • Be sure to calculate buffer capacity for acid & buffer capacity for base.
        • Answer all of the Post-Lab Questions.

  • Experiment #9: pH-monitored Titrations
    • Lab Handout - Updated Spring 2017 - We will be performing ONLY parts B&C of the experiment.
    • The possible unknown monoprotic acids for Part B of the pH titration experiment are:
      • lactic acid
      • crotonic acid
      • chloroacetic acid
    • The possible unknown diprotic acids for Part C of the pH titration experiment are:
      • oxalic acid
      • succinic acid
      • L-tartaric acid
        • pKa1 = 2.89
        • pKa2 = 4.40
  • Experiment #10: Determination of the Ksp of an Organic Salt
    • Lab Handout
      • Please prepare a standard prelab; however, the prelab question is NOT required.
    • Class Data
      • Be sure to include this data (adding to it the appropriate average/standard deviation analysis discussed in lab) along with your report!
    • Solubility (from the CRC Handbook of Chemistry & Physics):
      • KHT (Potassium Hydrogen Tartrate) = 0.42 g/100 mL at 15ºC
      • PbCl2 = 0.99g/100mL at 20ºC
  • Experiment #11: Determination of the Thermodynamics of the Dissolution of Borax

I will be updating some of the laboratory activities this semester.

    • 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 & LAB TEST REVIEW

  • Experiment #2 Practice:
    • Rework 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 #3 Practice:
    • Rework Prelab Questions
  • 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.
    • ANSWERS (for Week 4)
