Today was the second day of our “Mystery Liquids” lab, the day where students got to put their procedures into action. Through a combination of PH testing, observation, and reaction tests, students tried to classify each of the ten liquids. This wasn’t so easy. Not all acids are strong or produce big reactions; and bases can be equally difficult. Not to mention the neutral compounds that don’t react with anything!
Nevertheless, most groups were able to collect enough data to classify each of the liquids. Tomorrow, they will write a final draft of their lab report ending with their conclusions. At the end of class tomorrow, the answers will be revealed.
