In Mrs. Prescott’s CCP Chemistry class, students had the chance to explore the science behind carbonation by creating two beverages using drink mix packets. The experiment focused on the chemical reaction between citric acid and baking soda, which produces carbon dioxide gas—the same process that occurs in Fizzies or Pop-Rocks.

Each student group was tasked with making two beverages. One was carbonated by mixing citric acid and baking soda, while the other served as a control without carbonation. The key challenge was to accurately calculate how much citric acid was required to react with 1.50g of baking soda. Using stoichiometry and a balanced chemical equation, students determined the precise proportions necessary to produce enough carbon dioxide to carbonate the drink.

Students quickly learned that getting the proportions right was critical. If too much citric acid was added, the drink would be excessively sour. If the proportions were off, the drink would lack carbonation or have a soapy, bitter taste.

Once the drinks were made, students used tasting cups to sample their creations and compare results. They also had the opportunity to taste each other’s beverages, engaging in a hands-on way to apply their chemistry knowledge.

This experiment not only made chemistry fun but also reinforced important concepts about chemical reactions, stoichiometry, and precision in scientific experiments.
