Building a Colorimeter: A Demonstration with Alternative Materials in the Classroom

Key Points

This research aims to present a demonstration of building alternative colorimeters for educational settings.
Constructed two alternative colorimeters based on Duboscq’s design.
Tested performance against a commercial spectrophotometer.
Conducted experiments to compare concentration measurements.
Alternative colorimeters exhibited strong performance relative to the commercial spectrophotometer.

Abstract

Colorimetry is a technique based on Beer–Lambert’s law and applied to various fields of science to determine the concentration of substances. In this demonstration, two alternative colorimeters based on Duboscq’s colorimeter are built and tested. The alternative colorimeters demonstrated good performance when compared with tests conducted on a commercial spectrophotometer, suggesting that they could be used in high school and introductory science classes in higher education.
