Aspirin absorption in carbohydrate solutionsFeatured science projectScience project video


It is observed that the aspirin dissolved faster in the cup with water and the cup with sugar added to the water. The pH reading decreased at almost the same rate. However, the aspirin was slower to dissolve in the cup with the corn flour.
