Quantitative Analysis
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.
