# When sulfuric acid and copper (II) are allowed to react, copper (II) sulfate and water are formed. How do you write a balanced equation for this reaction?

$C u O \left(s\right) + {H}_{2} S {O}_{4} \left(a q\right) \rightarrow C u S {O}_{4} \left(a q\right) + {H}_{2} O \left(l\right)$
I always enjoyed doing this reaction as it is a beautiful reaction to do. You add the acid, and you get the lovely blue colour of the hexa-aqua ion, ${\left[C u {\left(O {H}_{2}\right)}_{6}\right]}^{2 +}$ as it sulfate salt. The reaction above is simply an acid base reaction.
