Question
A) The color of the solution changed from blue to pink, because lowering the temperature increased the collision frequency between CoCl2−4CoCl42−and H2OH2O.
B) The color of the solution changed from blue to pink, because cooling caused the equilibrium to shift to form the pink-colored Co(H2O)2+6Co(H2O)62+.
C)The color of the solution did not change, because more water was not added to the solution.
D)The color of the solution did not change, because heat is not released from this reaction.
