What is the purity test of synthesized aspirin and commercial aspirin?

### Comparison of Synthesized and Commercial Aspirin #### Synthesized Aspirin (Recrystallized) - **Trial 1:** - Mass of aspirin: 0.566 g - Volume of NaOH: 11.72 mL - **Trial 2:** - Mass of aspirin: 0.572 g - Volume of NaOH: 11.51 mL #### Commercial Aspirin - **Trial 1:** - Mass of aspirin: 0.368 g - Volume of NaOH: 6.80 mL - **Trial 2:** - Mass of aspirin: 0.364 g - Volume of NaOH: 6.50 mL ### Explanation This data compares two different types of aspirin: synthesized (recrystallized) and commercial. Each type was tested in two trials to measure the mass of aspirin used and the volume of NaOH required. The synthesized aspirin in both trials involved a larger mass and volume of NaOH compared to the commercial aspirin, indicating differences in composition or purity. The measurements are recorded in grams (g) for mass and milliliters (mL) for volume.
