Question

When the green solid of [crcl2(h2o)4]3 is dissolved in h2o the color of the solution is green. However, after a day the solution will turn violet. Based on what you have learned about ligands, what could explain this observation (the metal does not change)?

Answer 1

The color change observed in the [CrCl2(H2O)4]3- complex can be explained by the different ligands present in the solution.

Step-by-step explanation:

The color change observed in the [CrCl2(H2O)4]3- complex can be explained by the different ligands present in the solution. The initial green color is due to the presence of certain ligands, while the violet color that develops over time is caused by the presence of different ligands. Ligands are responsible for absorbing specific wavelengths of light, which gives rise to the observed color. In this case, the ligands in the initial complex absorb photons in the green range, while the ligands in the final complex absorb photons in the violet range.
