Chemistry-Study and teaching; Handouts; Solution (Chemistry)
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; 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.
Chemistry-Study and teaching; Handouts; Thermodynamics; First law of thermodynamics; Chemical equilibrium
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; 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...
Experiment in which the objectives are to determine the percentage copper in a brass sample from the amount of radioactivity that has been produced by bombardment with a beam of neutrons and to determine the half-life of an isotope from the rate at...
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; Chemical kinetics; Solution (Chemistry)
Experiment involving the study of the kinetics of the reaction between iron(III) and thiocyanate ions by the stopped-flow method, using the HiTech Stopped-Flow System and a digital oscilloscope.
