A blue compound called copper sulfate pentahydrate; the anhydrous form of this compound (copper sulfate) is white.
Why? What causes the color change when water molecules are removed?
Homework Answers
In most of the transition metal complexes colour arises due to d-d transition in accord with crystal field theory. In presence of water molecule, there occurs splitting of the d-orbital in to t2g (lower energy) and eg (higher energy) due to loss of degeneracy. As a result of the splitting of d-orbital a substantial transition of electron in between t2g and eg level leading to colour formation.
On the otherhand, in anhydrous copper sulfate, the degeneracy of the d-orbital is maintained and no such transition of electrons takes place and hence appears white.

When copper(II) sulfate pentahydrate is heated in air above 100C, it loses the water molecules and also its blue color. CuSO4•5H2O—>CuSO4 + 5H2O If 9.75 g of CuSO4 are left after heating 15.25 g of the blue hydrate, calculate the number of moles of water originally present in 15.25 g of the hydrate.

12 If white anhydrous copper(II) sulfate powder is left in the atmosphere it slowly absorbs water vapour giving the blue pentahydrated solid. Cuso (s) + SH,O(1) CuSO, SH,O(s) (anhydrous) (pentahydrated) It is difficult to measure the enthalpy change for this reaction directly. However, it is possible to measure the heat changes directly when both anhydrous and pentahydrated copper(II) sulfate are separately dissolved in water, and then use an energy cycle to determine the required enthalpy change value, AH,, indirectly.
