Carolina ChemKits®: Milk of Magnesia Rainbow



Grades 9-12. Introduce students to the significance of pH indicators with this colorful 2-part activity that explores solubility, equilibrium, Le Châtelier's principle, and acid-base chemistry. In Part 1, students investigate how changes in pH affect magnesium hydroxide's solubility, and then extend the investigation to magnesium hydroxide's solubility equilibrium. In Part 2, students design their own inquiry-based experiment to vary temperature and observe changes in solubility equilibrium. Great for engaging your students and exploring several difficult concepts. Materials are sufficient for 30 students working in groups of 3.
