  1. Put stoichiometric amounts of copper and sodium bisulfate in a test tube and heat it. The following reactions will take place. 4NaHSO4 --> 2Na2S2O7 + 2H2O 2Na2S2O7 --> 2Na2SO4 + 2SO3 2SO3 + Cu --> CuSO4 + SO2 (I skipped the step where the copper is oxidized for simplicity's sake and rewrote the equation accordingly) So the reaction produces copper(II)Sulphate and Sulfur Dioxide gas. Now you have a few options: 1) Run the SO2 through a hydrogen peroxide solution and cook it down (SO2 + H2O2 --> H2SO4)<---I did this one 2) Make a saturated copper sulfate solution and perform electrolysis with two copper electrodes 3) 2HCl + CuSO4 --> H2SO4 + CuCl2 I haven't done the second one and I don't know if the last one is even possible, but the first one definetely works
