Experiment with the goal of gaining an understanding of anodic stripping voltammetry and an understanding of the factors involved in performing quantitative analytical determinations, through the determinations of amounts of copper.
Handout explaining systematic and random errors, precision versus accuracy, significant figures, absolute and relative error, propagation of errors, measurement distribution, etc.

Introduction. In class we observed that no reaction goes to completion and have discussed qualitatively the consequences of this insight. It is also possible to deal quantitatively with chemical equilibria. The chemist's approach should start with...

Experiment in which the objective is to separate, by gas chromatographic techniques, a mixture of the four isomeric butyl alcohols and to determine the percentage of each an unknown mixture.
Chemistry-Study and teaching; Absorption spectra; Molecular spectroscopy; Thermodynamics; Statistical mechanics
Experiment involving an introduction to molecular spectroscopy and the extraction of molecular parameters and thermodynamic properties from an analysis of the vibrational fine structure of an electronic band spectrum of gaseous iodine.
Chemistry-Study and teaching; Absorption spectra; Solution (Chemistry); Spectroscopy, Atomic absorption
Experiment consisting of preparing a series of standard solutions containing iron and solutions of metallic alloy samples, then measuring the absorption of light by the atoms of the element when the solutions are aspirated into a flame.

Introduction: Use the approach outlined in the handout "How To Solve Equilibrium Problems" to solve the following problems related to the hydrogenation reaction. Use partial pressure as the concentration unit for the gaseous species.
Chemistry-Study and teaching; Handouts; Solution (Chemistry); Volumetric Analysis
Experiment in which the objective is to apply the methods of volumetric analysis to the determination of the percentage of potassium hydrogen phthalate in a sample, the molecular weight and ionization constant of an unknown weak acid, and the...
Chemistry-Study and teaching; Handouts; Thermodynamics; Second law of thermodynamics; Chemical equilibrium
Introduction: The First Law of Thermodynamics places important restraints on the path that can be taken by a system but it does not define the path. For example, the First Law does not rule out the possibility of warming oneself by sitting on a...
