Week 1: Chemical Kinetics 1
By observing the progress of the reaction over time, you will determine the rate law and confirm the mechanism of the reaction between cyclohexanone and iodine.
Week 2: Chemical Kinetics 2
In this week's lab, you will further analyze the results of last week's experiments and you will carry out experiments to determine the temperature dependence of the reaction rate constant.
Week 3: Spectrum of the Hydrogen Atom
In this experiment you will use a meterstick spectroscope to observe the emission spectrum of hydrogen, sodium, neon, helium, and mercury.
Week 4: Spectra of Conjugated Dyes & Beer's Law of Koolaid
Description to come.
Week 5: Coordination Chemistry: Synthesis
In this week's experiment you will synthesize the coordination compound aquapentaammine-cobalt (III) nitrate, [Co(NH3)5H2O](NO3)3
Week 6: Coordination Chemistry: Colorimetric and Gravimetric Analysis
This week you will analyze the coordination compound that you synthesized last week. You will determine the weight percent cobalt in in your sample by colorimetry. You will also determine the weight percent water in your sample by observing the change in sample mass when the water is driven off by heat.
Week 7 Part 1: Coordination Chemistry: Acid/Base Analysis
In this experiment, you will examine the acidity of your coordination complex's water ligand. You will determine the acid dissociation constant, Ka, of the complex by titrating it with base.
Week 7 Part 2: Coordination Chemistry: Preliminary Kinetics Measurements
A second part of today's lab work is to perform initial experiments on the mechanism of ligand exchange reactions.
Week 8: Coordination Chemistry: Kinetics Measurements
This week you will complete your study of the mechanism of ligand exchange between your complex, Co(NH3)5H2O, and the nitrite ion, NO2- The reaction will be followed colorimetrically and the rates of exchange and ligand isomerization will be measured.
