If equal volumes of differently colored solutions are poured into opposite sides of a shallow pool of water, what will be the result at equilibrium?
A) Each solution will be uniformly distributed in the side of the pool into which it was poured.
B) The solutions will be uniformly distributed throughout the pool.
C) Each solution will have moved against its concentration gradient.
D) The concentration of each solution will be higher in one side of the pool than in the other.
E) The solutions will have sunk to the bottom of the pool and remained separate.

At equilibrium, the solutions will diffuse and mix with the surrounding water, resulting in a uniform distribution throughout the pool. Since the solutions are poured in equal volumes, there is no concentration gradient to drive the solutions to one side of the pool. Additionally, the solutions will not sink to the bottom and remain separate because of the process of diffusion.
