Experiment 1: Density of a Liquid and a Solid General Chemistry I and II Lab Manual Dakota State University Page 48 of 232 Experiment 1:Density of a Liquid and a Solid Purpose (1) To practice the procedures commonly used in a laboratory (2) To learn how to use some of the common laboratory devices (3) To distinguish between chemical and physical properties Pearly Having characteristics of pearls Background: See “Basic Laboratory Procedures”: pipette, graduated cylinder, balance Introduction In just about any lab manual you look at, you will notice that the first experiment is something like the determination of the density of various objects. The reason for this is quite simple to understand: the author wants you to learn how to use some of the basic pieces of the lab while performing an experiment that is relatively safe. In time, you will be performing experiments that do, out of necessity, have inherent dangers, but before you do, you want to be comfortable with your own laboratory skills through practice.
