Aspirin (acetylsalicylic acid) might be the most used and abused non-prescription drug. Using aspirin tablets brought from home, students analyze and compare them with the Brand X aspirin included in this Lab-Aid.
They determine the percentage of aspirin and filler components in a tablet, check pH, and calculate the per-pill cost. Students draw conclusions on which aspirins are better, which are safer, and which do nothing at all. This consideration brings real-world questions into the science classroom. Extension activities are possible with this kit.
