Drug Analysis

For this experiment first, we got in groups of four. At each group’s station was a sample of simulated drugs and we had to determine if it was cocaine, LSD, or other. Each groups mixed a small amount of the simulated drugs with water in a beaker. Then we put a small drop of the solution into a petri dish and tested it with pH strips, recording its pH. We did this two more times with the cocaine indicator and the LSD indicator. Then the groups rotated and tested the next sample until we had tested all the samples. In this experiment we learned how to determine if a substance is illegal drugs or not.
