Introduction
Occasionally, despite the best efforts of the most meticulous workers in a chemistry lab, containers with no labels are discovered. When this happens, there are two major concerns: making sure all the workers in the lab are safe and identifying the contents of the container.
In the scenario presented in this investigation, several unlabeled bottles have been found in your laboratory stockroom. Each unlabeled bottle contains a solid substance. The lab director, through some very careful research, has narrowed the list of possible substances in the bottles.
