Experiment 19, Equilibrium Constants and LeChatelier's Principle: CoCl2
Purposed topic: Equilibrium
Objective: To determine whether or not LeChatelier's principle is consistent
List of factors that will be used for testing
- 1. Addition of water
- 2. Addition and removal of Chloride
- 3. Changes in temperature
Brief Background Information
- Cobalt chloride in water is a well-known equilibrium system because two spices in which containing the same amount of cobalt can have different colours
- The equilibrium expression for this system is
- [Co(H2O)6]2+(aq) + 4Cl-(aq) ↔ [CoCl4]2-(aq) + 6H2O(l)
