Three bottles of aqueous solutions are discovered in an abandoned lab. The solutions are green, yellow, and purple. It is known that three complex ions of chromium (III) were commonly used in that lab: [Cr(H20)6]3+, [Cr(NH3)6]3+, and [Cr(H20)4Cl2]+. Determine the likely identity of each of the solutions.
