When you mix copper sulfate (CuSO₄) with sulfuric acid (H₂SO₄), you typically get a solution that contains copper sulfate in sulfuric acid as the medium. If the concentrations are appropriate, there are no significant new chemical reactions, and the copper sulfate remains largely intact in solution.
However, if you heat the mixture, or if the concentration of sulfuric acid is very high, you might also promote the formation of complex ions
