Consider the following equilibrium using LeChatelier’s Principle – note the colors: Co(H2O)62+ (aq) + 4Cl– (aq) ⟷ CoCl42– (aq) + 6H2O (l) Pink Blue What color will the solution turn if the following stresses are applied and why? HCl (aq) is added. CoCl42– is removed. Pb2+ is added to the system. Lead reacts with chloride ions to form solid PbCl2. The solution turns pink when the solution is heated and turns back blue when placed in an ice bath. Based on this information, on which side of the reaction arrow does the word "heat" belong?

Question
Consider the following equilibrium using LeChatelier’s Principle – note the colors:
Co(H2O)62+ (aq) + 4Cl– (aq) ⟷ CoCl42– (aq) + 6H2O (l)
Pink Blue
What color will the solution turn if the following stresses are applied and why?
- HCl (aq) is added.
- CoCl42– is removed.
- Pb2+ is added to the system. Lead reacts with chloride ions to form solid PbCl2.
- The solution turns pink when the solution is heated and turns back blue when placed in an ice bath. Based on this information, on which side of the reaction arrow does the word "heat" belong?
