$CuSO_4$ (anhydrous)

Vedclass · Answer

(B) Hydrated copper sulphate $CuSO_4 \cdot 5 H_2 O$ is blue in colour due to the presence of water ligands which cause splitting of $d$-orbitals,facilitating $d-d$ transitions.Anhydrous copper sulphate $CuSO_4$ is colourless because,in the absence of ligands,the $d$-orbitals do not split,making $d-d$ transitions impossible.Therefore,option $(B)$ is correct.
