Introduction. The purpose of this short discussion is to provide a correct yet understandable introduction to thermodynamics. It is intended to replace and not complement the material in your text. The author is schooled in the Oberlin school of...
Chemistry-Study and teaching; Voltammetry; Electrochemistry; Solution (Chemistry)
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.
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...
Handout from the laboratory manual explaining curve fitting and the method of least squares. Included is a least squares exercise using Microsoft Excel.
Chemistry-Study and teaching; Adsorption; Molecular sieves; Gases
Experiment involving studying the adsorption of gaseous nitrogen and dimethyl ether on a molecular sieve; it also provides experience with manipulations on a vacuum line.
Chemistry-Study and teaching; Molecular rotation; Spectroscopy, Nuclear magnetic resonance; Chemical kinetics
Experiment involving learning how kinetic information can be obtained from an NMR line shape and determining the activation parameters for internal rotation of the N,N-dimethylamino group in N,N-dimethylacetamide.
Handout explaining systematic and random errors, precision versus accuracy, significant figures, absolute and relative error, propagation of errors, measurement distribution, etc.
Chemistry-Study and teaching; Spectroscopy, Nuclear magnetic resonance
