The Separating a Synthetic Pain Relief Mixture Inquiry Lab Solution for AP® Chemistry explores physical properties of a synthetic mixture to determine its percent composition while integrating solubility and acid–base reaction concepts.
Includes access to exclusive FlinnPREP™ digital content to combine the benefits of classroom, laboratory and digital learning. Each blended learning lab solution includes prelab videos about concepts, techniques and procedures, summary videos that relate the experiment to the AP® exam, built-in student lab safety training with assessments, and standards-based, tested inquiry labs with real sample data. FlinnPREP™ Inquiry Lab Solutions are adaptable to you and how you teach with multiple ways to access and run your AP® labs.
Big Idea 3, Investigation 9, Primary Learning Objective 3.10
Most over-the-counter (OTC) drugs are mixtures of active drug ingredient(s) and binders with a variable composition. Investigate the physical properties of ingredients in a synthetic pain relief mixture and determine its percent composition.
In the introductory activity, students test the solubility of each possible OTC component in ethyl acetate and in an aqueous solution of sodium bicarbonate. Using these results, students design of a flow chart procedure to separate the components and determine the amount of each. Optional extension activities include varying the composition of the OTC mixtures and analyzing consumer samples. Students may also measure the melting points of the isolated components to confirm their identity.
This advanced inquiry lab integrates student understanding of solubility and acid–base chemical reactions.
Complete for 24 students working in pairs. Perform this experiment in a fume hood or well-ventilated lab.
