Measuring the Density of a Sugar Solution: A General Chemistry Experiment Using a Student-Prepared Unknown
Peterson, Karen I.
Journal of Chemical Education, v85 n8 p1089-1090 Aug 2008
The experiment developed in this article addresses the concept of equipment calibration for reducing systematic error. It also suggests simple student-prepared sucrose solutions for which accurate densities are known, but not readily available to students. Densities are measured with simple glassware that has been calibrated using the density of water. By careful work, students can determine the density to within 0.5%. This allows accuracy to be a major component of the final grade. (Contains 1 figure and 2 notes.)
