Kinetic Analysis of Amylase Using Quantitative Benedict's and Iodine Starch Reagents  Beverly Cochran, Deborah Lunday, and Frank Miskevich
This laboratory emphasizes that enzymes mediate the conversion of a substrate into a product and that either the concentration of product or reactant may be used to follow the course of a reaction. It does so by using an inexpensive scanner and open-source image analysis software to quantify amylase activity through the breakdown of starch and the appearance of glucose.

Using Visible Spectrophotometers and pH Measurements To Study Speciation in a Guided-Inquiry Laboratory   William H. Otto, Cynthia K. Larive, Susan L. Mason, Janet B. Robinson, Joseph A. Heppert, and James D. Ellis
A collective-effort, guided-inquiry laboratory investigation was developed for the second-semester general chemistry laboratory for the purpose of increasing student conceptual understanding of equilibrium and speciation phenomena. This investigation required students to employ the chemical indicator phenol red in phosphate buffer solution, computer interfaced pH probes, and visible spectrophotometers. Through a combination of potentiometric and visible absorption measurements, the students determined the pH conditions that alter equilibrium concentrations of multiple species (colored and transparent) in solution.

Making and Using a Sensing Polymeric Material for Cu2+: An Introduction to Polymers and Chemical Sensing  Jean R. Paddock, Anne T. Maghasi, William R. Heineman, and Carl J. Seliskar
In this experiment, students will be introduced to concepts of polymer chemistry, chemical sensors, metal chelates, spectroscopy, and quantitative analytical methods. A polymer network is generated by students and consists of crosslinked poly(vinyl alcohol) blended with the polyelectrolyte poly(acrylic acid), which is then doped with the spectroscopically-active chelating agent PAN, 1-(2-pyridylazo)-2-napthol. All components of this hydrogel serve as an ion-exchange medium trapping cations that, when exposed to solutions of 2+ metals, can act as a material in a chemical sensor.

Synthesis and Physical Properties of Liquid Crystals: An Interdisciplinary Experiment  Gerald R. Van Hecke, Kerry K. Karukstis, Hanhan Li, Hansford C. Hendargo, Andrew J. Cosand, and Marja M. Fox
This experiment features an investigative approach designed for the introductory science or engineering major and integrates concepts in the fields of chemistry, biology, and physics. Derived from faculty research interests, this novel experiment gives students the opportunity to draw conclusions from tests performed to illustrate the connection between molecular structure and macroscopic properties. The chemical synthesis of the compounds studied further enhances the connection between molecular structure and macroscopic physical properties. The results of two separate physical measurements, refractometry and absorption spectroscopy, are combined to calculate a microscopic, but very practical, property of chiral nematic liquidsthe pitch of the helix formed in the liquid crystalline phase.

Kinetics of Alcohol Dehydrogenase-Catalyzed Oxidation of Ethanol Followed by Visible Spectroscopy  Kestutis Bendinskas, Christopher DiJiacomo, Allison Krill, and Ed Vitz
A two-week biochemistry experiment was introduced in the second-semester general chemistry laboratory to study the oxidation of ethanol in vitro in the presence of the enzyme alcohol dehydrogenase (ADH). This reaction should pique student interest because the same reaction also occurs in human bodies when alcoholic drinks are consumed. Procedures were developed to follow the biochemical reaction by visible spectroscopy and to avoid specialized equipment. The effect of substrate concentration on the rate of this enzymatic reaction was investigated during the first week. The effects of temperature, pH, the specificity of the enzyme to several substrates, and the enzyme's inhibition by heavy metals were explored during the second week.

Analog Spectrophotometers in the Digital Age: Data Acquisition on a Budget  Alexander Y. Nazarenko and Natalie A. Nazarenko
In this article we describe how to employ an inexpensive analog-to-digital converter and a user interface to Microsoft Excel to make a useful computerized spectrophotometer. Readily available types of data loggers, Vernier LabPro and digital multimeters with an RS-232 interface, were utilized. The proposed design does not compromise the quality of the measurements. The conversion of the data to the Microsoft Excel format makes it a convenient tool for a wide range of data processing applications.

A Simple Protein Purification and Folding Experiment for General Chemistry Laboratory  Robert Bowen, Richard Hartung, and Yvonne M. Gindt
A simple procedure for the crude purification of a chromoprotein suitable for a general chemistry laboratory. The protein, phycocyanin, is easy to purify and very stable. It contains a chromophore that can serve to report the integrity of the protein structure: the chromoprotein is dark blue when the protein is folded in its native conformation, and it turns a very pale blue when the protein is unfolded or denatured.
