Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic. Once that skill is learned they can move on to test some common items that would be found around their house to determine if they are acids or bases. Optional: Extra litmus paper is included to test more items either from home or around the school building for a greater understanding of acids and bases. The activity contains enough materials for 6 groups of students.

Safety Data Sheet

Once the Grignard reagent is prepared, it can be used to prepare the target compound. In this experiment the target compound is a carboxylic acid. To prepare a carboxylic acid, the Grignard reagent is carboxylated in a reaction with dry ice. After the reaction is complete, hot water is added to evaporate any remaining solvent. Acid is added to dissolve the magnesium salts and liberate the carboxylic acid. Once the solution is cooled, the acid can be collected. In this experiment, we will prepare a carboxylic acid (benzoic acid) by the Grignard method.
