Here, students determine aspirin acetylsalicylic acid mass in pharmaceutical tablets using a colorimetric method.
Aspirin, salicylate, and salicylic acid do not absorb visible light. Thus, in alkaline medium, acetylsalicylic acid was hydrolyzed to salicylate; then, it was reacted with an acidic Fe III solution, and a violet complex was formed.
Quantitative analysis was carried out using absorbance measured at nm standard method and digital images obtained with a flatbed scanner proposed method.

Our goal was to design a portable, cost-effective, and user-friendly platform and to develop an experimental methodology that can easily be applied to any research and education laboratory using just a flatbed scanner.
