You are working with the following equilibrium system in which one chromium complex is blue and one chromium complex is purple. The system is at equilibrium and is currently purple.
Predict how the color will change if solvent is allowed to evaporate from the system. Hint: Think about how solvent evaporation will affect the concentration of all aqueous species, and how that will affect the equilibrium position.
[Cr(H2O)6]3+ (aq)+ 6 NH3 (aq)=[Cr(NH3)6]3+ (aq)+ 6 H2O (l)
Blue Purple
A.The solution will become a lighter purple.
B.The solution will not change colors.
C.The solution will turn from purple to blue.
D.The solution will become a darker purple.
