Question
When blue solid CuSO4•5 H2O is heated, it turns white. Which is the best explanation for this observation?
A.✓ Correct
Heating causes water molecules bonded to copper to be replaced by sulfate, lowering the energy of the light absorbed.
B.
Heating causes an expansion of the lattice, leading to a decrease in the coordination number of copper and raising the energy of the light absorbed.
C.
Heating causes reduction of copper(II) to copper(I).
D.
Heating causes reduction of sulfate to sulfite.
