Automation of an acid-base volumetric titration as an educational prototype

Abstract

The use of prototypes in the teaching-learning process promotes in students a greater interest in learning Chemistry, thereby enhance, their capacity for innovation, creativity and problem solving. The use of the Arduino microcontroller and its sensors are widely used for the design of different prototypes, due to their low cost, in addition to having simple programming and open-source software. For the present research, an educational prototype, was developed which performs an acid-base volumetric titration in an automated, way which is made up of mechanical, electrical, as well as 3D printing parts, in consequence can be implemented and improved in engineering careers where chemistry is a fundamental subject.
