Virtual Lab: Cobalt Chloride and Le Chatelier’s Principle

Colorful cobalt complexes make a great way to learn about Le Chatelier! Eager chemists explore equilibrium through a virtual lab. Individuals use solutions with two different concentrations and observe the color changes that indicate shifts in equilibrium.

Instructional Ideas
  • Get the lesson started with a video from Flinn Scientific 
  • Perform the reactions as demonstrations after the class has completed the virtual lab
Classroom Considerations
  • Students should be comfortable with ion complexes and solution vocabulary
  • Make sure the class understands the controls in the simulation before getting started
  • The solutions for the lab are pre-made, allowing more time for pupils to focus on Le Chateleir's Principle
  • Background information is well-written and great for learners new to equilibrium reactions
  • None
