  • Resumen
    • One of the topics that chemistry teachers have a great challenge introducing is chemical equilibrium. When being introduced to chemical equilibrium, many students have difficulties in understanding that some reactions do not go to completion, as this contrasts most of their supposed prior experiences in chemistry lessons. Students may also struggle with the existence of dynamic equilibrium in which reactants and products constantly transform into each other in a nonvisible manner. The goal of this general chemistry demonstration is to provide teachers with an effective method to help introduce the difficult idea of chemical equilibrium as well as connect chemical equilibrium to acid–base chemistry more successfully. This demonstration will allow students to develop a better understanding of the dynamic nature of chemical equilibrium and Le Chatelier’s Principle by letting them interpret measured pH values and observe correlated color changes before and after the addition of different reagents that shift the chemical equilibrium.
