In class we made copper (||) sulfate crystals, from adding copper (s) to sulfuric acid (aq). To make CuSO4.5H2O the questions asked were:

1) The Copper sulfate (CuSO4) may of contained copper hydroxide (Cu(OH)2) why did this not effect the molar mass of CuSO4.5H20 (which is the product of the reaction)

2)why was only copper sulfate formed and no other substance/compound
