QUESTION:
Most transition metal ions are colored. For example, a solution of \(\mathrm{CuSO_4}\) is blue. How would you show that the blue color is due to the hydrated \(\mathrm{Cu^{2+}}\) ions and not the \(\mathrm{SO_{4}^{2-}}\) ions?
ANSWER:Step 1 of 2
Here, we explain the blue color is due to the hydrated ions and not the ions.
Presence of d-d transitions in Transition metal ions exhibits colour.
Due to the hydrated ions are present in the copper sulfate solution exhibits blue colour.
