Why colour of anhydrous copper sulphate is white? In hydrated CuSO4 the water molecules surrounding the Central metal (Cu) function as ligands which bring d-d transition and hence emits blue colour in visible region due which hydrated CuSO4 appears blue and as anhydrous CuSO4 doesn’t have any water of crystallisation hence remains white in colour.
Why anhydrous copper sulphate is Colourless But hydrated copper sulphate is Coloured? In anhydrous CuSO4 there is, in practice, zero crystal (ligand) field, so d-orbitals of Cu(II) in anhydrous CuSO4 are degenerate, so no d-d transitions possible, hence white, however, in hydrated CuSO4 there are four water molecules (ligands) surrounding the Cu(II) ion, resulting in lifting of d-orbitals degeneracy, …
Why does CuSO4 turn white when heated? When hydrated salt of copper sulphate is heated strongly, blue copper sulphate crystals turn white (due to the loss of water of crystallization).
What is the colour and structure of anhydrous copper sulphate? Now, when this hydrated copper (II) sulfate (CuSO4. 5H2O) or blue vitriol is heated at high temperatures, it loses its water of crystallization (5H2O) and forms amorphous copper sulfate (CuSO4). The blue vitriol turns white upon heating. Hence, the color of amorphous copper sulfate (CuSO4) is white.

Why does copper have an unusual electron configuration?
There are two main exceptions to electron configuration: chromium and copper. In these cases, a completely full or half full d sub-level is more stable than a partially filled d sub-level, so an electron from the 4s orbital is excited and rises to a 3d orbital.
