Question

What products result when copper sulfate is dissolved in water?

Answer 1

`Cu^(2+)`, and `SO_4^(2-)`.

Explanation:

Anhydrous copper sulfate is white; in aqueous solution, the `Cu^(2+)` ion gives a beautiful blue colour due to formation of the complex ion, `[Cu(OH_2)_6]^(2+)`.

The sulfate anion, is of course along for the ride.
