Introducing Acid–Base Titration on Paper-Based Analytical Devices in a High-School Chemistry Laboratory for the Determination of Acetylsalicylic Acid

Abstract In this study, paper-based analytical devices (PADs) were used to introduce a simple, rapid, portable, and low-cost acid–base titration method in high school chemistry laboratories. Students performed conventional and paper-based titrations to determine the amount of ace...
