Dartmouth College: Chem Lab: Natural Salt Solutions 1: Ion Exchange
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.
Dartmouth College
Dartmouth College: Acids, Bases, and Buffers 1: Monoprotic and Polyprotic Acids
In this experiment, you will explore the behavior of the monoprotic acid (acetic acid) and the polyprotic acid (phosphoric acid). By titrating, you will examine the acid and conjugate base species present across the pH scale and the...
Dartmouth College
Dartmouth College: Chem Lab: Chemical Kinetics 1
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.
Dartmouth College
Dartmouth College: Chem Lab: Chemical Kinetics 2
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.
Dartmouth College
Dartmouth College: Chem Lab: Spectrum of the Hydrogen Atom
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.
Dartmouth College
Dartmouth College: Chem Lab: Spectra of Conjugated Dyes & Beer's Law
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...
Dartmouth College
Dartmouth College: Chem Lab: Coordination Chemistry 3.2
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.
Dartmouth College
Dartmouth College: Chem Lab: Coordination Chemistry: Kinetics of Ligand Exchange
In this experiment, you will complete the study of the mechanism of ligand exchange. The reaction will be followed colorimetrically and the rates of exchange and ligand isomerization will be measured. Requires Java plug-in.
Dartmouth College
Dartmouth College: Chem Lab: Coordination Chemistry 3.1: 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 of the complex by titrating it with a base. There are eight weeks of experiments in this series.
