Question
Would you expect salts of the gold(I) ion, $\mathrm{Au}^{+}$ , to be colored? Explain.
Step 1
When light of suitable frequency is passed through the solution of transition metal ions, the energy gets absorbed and electrons move from lower energy d-orbitals to higher energy d-orbitals. If the frequency of the absorbed photon lies in the visible region, the Show more…
