The pink and blue species below form a violet colored mixture at equilibrium: [Co(H₂O) ₆]²⁺ (aq) + 4 Cl^- (aq) ⇌ [CoCl₄]^2- (aq) + 6 H₂O (l)
(pink) (blue)
If the concentration of [Co(H₂O) ₆]²⁺ is increased,what happens to the solution?

Question

Quizplus · Accepted Answer

According to Le Chatelier's principle, if the concentration of a reactant or product is increased, the equilibrium will shift in the direction that minimizes the effect of that change. In this case, increasing the concentration of [Co(H₂O)₆]²⁺ will shift the equilibrium to the right, favoring the formation of [CoCl₄]^2- and consuming Cl^- and H₂O. Therefore, the concentration of [CoCl₄]^2- will increase.
