# What products result when copper sulfate is dissolved in water?

$C {u}^{2 +}$, and $S {O}_{4}^{2 -}$.
Anhydrous copper sulfate is white; in aqueous solution, the $C {u}^{2 +}$ ion gives a beautiful blue colour due to formation of the complex ion, ${\left[C u {\left(O {H}_{2}\right)}_{6}\right]}^{2 +}$.
