Dartmouth College: Chem Lab: Coordination Chemistry: Kinetics of Ligand Exchange

In this experiment, you will study the reaction between your cobalt complex and the nitrite ion. The nitrite ion can exchange with a water ligand and the mechanism of this ligand exchange will be investigated. Requires Java plug-in.

In this four-week experiment, you will synthesize a compound and purify it in week 1. In week 2, you will assay it for purity by colorimetric analysis and by gravimetric analysis. In week 3, you will analyze your compound by titration of...

In this experiment, you will examine the acidity of your coordination complex's water ligand. You will determine the acid dissociation constant of the complex by titrating it with a base. There are eight weeks of experiments in this series.

In this experiment, you will concentrate on understanding the chemistry of ion exchange and estimate the capacity of an ion exchange column from your observations.

In this lab experiment students are asked to determine the standard molar enthalpy of formation of magnesium oxide, MgO. Students are asked to use Hess's Law and the enthalpy changes of several other solution reactions during this...

This lab further analyzes the results of the experiments carried out in Chemical Kinetics 1. In addition, you will carry out experiments to determine the temperature dependence of the reaction rate constant. Requires Java plug-in.

In this experiment, you will determine the rate law and confirm the mechanism of the reaction between cyclohexanone and iodine. Requires Java and QuickTime plug-ins to access some features.

In this experiment, you will use a meterstick spectroscope to observe the emission spectrums of hydrogen, sodium, neon, helium, and mercury. Requires Java plug-in.

In the first part of this lab, you will measure the absorption spectra of two conjugated dyes and compare the results to the theoretical predictions of a particle-in-a-box model. In the second part of the experiment, you will identify...

A titration is a method of analysis that will allow you to determine the precise endpoint of a reaction and therefore the precise quantity of reactant in the titration flask. This site demonstrates how to correctly perform this analysis.
