Use the chemical equation to answer the question.
Co(H2O)62+ + 4Cl– + heat ⇄ CoCl42–+ 6H2O
Cobalt ions form complex ions with water and chloride. The Co(H2O)62+ ions are pink, and the CoCl42– ions are blue. A scientist creates a solution that is purple at equilibrium. How can the scientist make the solution more pink?

Answer: by adding water H2O.
Reason: 6 H2O is a product, so adding water shifts the equilibrium left (Le Chatelier’s principle), producing more Co(H2O)6^2+ (pink). Adding heat, HCl, or Co(H2O)6^2+ would shift it toward the blue CoCl4^2–.
