Ba2+ (aq) + SO42- (aq) → BaSO4 (s)
Blue is the solution's color When blue CuSO4.5H2O (copper(II) sulfate pentahydrate) is dissolved, the solution turns blue. When white CuSO4 (anhydrous copper(II) sulfate) is dissolved, the solution turns also blue.
Blue vitriol is the obsolete name of copper(II) sulfate - CuSO4.
This requires a knowledge of crystal field theory. The d electrons that surround copper can be excited by light. This absorption of red/yellow causes the colour to appear blue.
Yes. Yes it is. :)
Copper(II) sulfate has the formula CuSO4.

Copper sulfate is not black. Combined with water, as hydrated copper sulfate, it is blue. Without water, as anhydrous copper sulfate, it is white.
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.
