Overview Adapted from Scientific American and Connections Education In this colorful experiment, students extract red cabbage indicator (an anthocyanin) with isopropyl alcohol or water. Students then create a series of solutions of […]
Use the (really fun!) reaction between the sodium bicarbonate in Alka-Seltzer tablets and vinegar to explore stoichiometry, percent composition, and limiting reactants. This experiment is easily and safely reproduced at home using […]
