Dartmouth College: Chem Lab: Coordination Chemistry 3.2

For Students 9th - 10th
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: Chem Lab: Coordination Chemistry: Kinetics of Ligand Exchange

For Students 9th - 10th
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: Chem Lab: Coordination Chemistry 3.1: Acid/base Analysis

For Students 9th - 10th
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.

Dartmouth College: Acids, Bases, and Buffers 1: Monoprotic and Polyprotic Acids

For Students 9th - 10th
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: Chem Lab: Chemical Kinetics 1

For Students 9th - 10th
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.
Activity
Dartmouth College

Dartmouth College: Chem Lab: Chemical Kinetics 2

For Students 9th - 10th
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.
Activity
