Copper(II) sulfate is blue because it absorbs light in the red region of the spectrum, giving it a blue color. The copper ion in the compound reflects blue light, which is why we perceive it as blue.

Is cupric sulfate blue?

Most people think that Cupric sulfate or Copper(II) sulfate, is blue in colour. But actually it is not. Blue colour in Copper(II) sulfate is due to the presence of Water molecules in it. This form is called Copper(II) sulfate Pentahydrate[CuSO4.5H2O], which most people see. If it does not have any water molecules in it, the thing is in pure state and is White in colour. This form is Anhydrous Copper(II) sulfate[CuSO4]. This form is rarely seen, because it can absorb water itself from the nature and become blue in colour. So from this we know that very pure Copper(II) sulfate is not blue, But its Pentahydrate form is blue.
