Explore the fundamentals of electrolysis and redox reactions with this colorful, intuitive, multipart activity. First, students observe the electrolysis of water using a universal indicator solution and connect their observations to the chemical changes occurring at each electrode. Next, they investigate the differences between electrolytes in distilled and tap water. In the final activity, students study the electrolysis of aqueous potassium iodide and extend their learning to predict the half-reactions of similar halogen-containing compounds. Kit contains sufficient materials for a class of 30 students working in pairs.
