Debunking Titration Endpoint Myths: Insights From Project-Based Learning
摘要
The volumetric analysis is a fundamental analytical technique in chemistry that students typically begin learning in higher secondary school. However, students frequently focus on observing the colour change during titration but fail to grasp the underlying concepts related to the theory of acid-base indicators. To address this issue, a project-based learning approach using natural indicators has been employed to elucidate the role of indicators. This pedagogy aims to help students understand the concepts and instil confidence in designing and rationalizing experiments.
