Chapter 8, Problem 8.119QP

Interpretation Introduction

Interpretation:

The blue color in $CuS{O}_4$ is due to the hydrated $C{u}^{2+}$ ions and not the $S{O}_4^{2-}$ ions has to be shown

Concept Introduction:

When the electron gets excited from lower to higher levels the energy gap lies in visible region was absorbed and the corresponding complementary color was shown by the complex.

Generally, the transition metal ions give color to the compound due to the d–d transition.
