Carolina Chemonstrations®: Under Pressure Kit

Item # 840364 Exclusive

Bring a dynamic example of Le Châtelier’s principle to your classroom with this teacher-led, student-engaged demonstration kit. Students observe a shift in the solubility of carbon dioxide in seltzer water in action as pressure is applied to the system. A pH indicator gives visual clues to the equilibrium change. This demonstration requires approximately 10 min, and materials are sufficient for 5 demonstrations.

  • Observe the effect of pressure on a system at equilibrium
  • See Le Châtelier’s principle in action
  • Explain and illustrate the equilibrium shift on a molecular level

Students are active participants in this demonstration of Le Châtelier’s principle and equilibrium. After making predictions about what will happen, they observe a color change indicating an equilibrium shift in the solubility of carbon dioxide in seltzer water. Students explain on a particulate level why a change in pressure resulted in the pH change and answer Big Picture Questions that solidify the underlying science concepts. This demonstration requires approximately 10 min, and materials are sufficient for 5 demonstrations.
