CuSO 4 .5H 2 O is blue in color while CuSO 4 is colorless. Why?

Options

  1. APresence of water molecules in CuSO 4 .5H 2 O induces ligand field splitting.
  2. BCuSO 4 undergoes decomposition in the absence of water, leading to loss of color.
  3. CThe crystal field stabilization energy of CuSO 4 .5H 2 O results in a color change.
  4. DCuSO 4 has a lower coordination number, preventing the manifestation of color.

Correct answer

A. Presence of water molecules in CuSO 4 .5H 2 O induces ligand field splitting.

Step-by-step solution

Correct Option is : (A) Presence of water molecules in CuSO 4 .5H 2 O induces ligand field splitting.
