Activities

ChemEd X activities are student-centered resources intended to aid learning chemistry topics.

ChemEd X encourages engaging activities where students (with guidance from the teacher) pose questions, analyze data, and make observations to offer a plausible explanation supported by data and consistent with physical observations.

The major component of a non-carbonated drink such as KoolAid or a similar beverage is usually a fruit acid, either citric acid or malic acid. The titratable acid (H+) concentration of such drinks has been found to be in the range of 0.02 to 0.04 M. A weak acid-strong base titration of these drinks with 0.1 M NaOH solution is feasible as a student exercise. The use of such drinks as reagents is safe, convenient, and inexpensive. Experiment instructions are included.
