CuSO4.5H2O (s) ⇌ CuSO4 (s) + 5H2O (g)
on heating copper sulphate the hydrous / hidrated crystals of copper change into coloueless cause the water molecules assioted with it evaprates and copper sulphate turns anyhydrous thus changing in to colourless.
and
when we add water into anhydrous copper sulphate solution changes to Blue this shows that coloured hydrated copper sulphate has regained
