Carbohydrates Dehydration of sucrose, Fehling's test, Benedict's test, osazone formation, destructive distillation of wood, oxidation of sucrose with potassium chlorate, and guncotton are demonstrated.
Measuring the Density of a Sugar SolutionKaren I. Peterson This experiment addresses the concept of equipment calibration for reducing systematic error. Students prepare and measure the densities of sucrose solutions with simple glassware that has been calibrated using the density of water. By careful work, students can determine the density to within 0.5%. allowing accuracy to be a major component of the final grade. Peterson, Karen I. J. Chem. Educ.2008, 85, 1089.
Kinetic Analysis of Amylase Using Quantitative Benedict's and Iodine Starch ReagentsBeverly 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. Cochran, Beverly; Lunday, Deborah; Miskevich, Frank. J. Chem. Educ.2008, 85, 401.
