...ell it is used for industrial purposes (Hardwood, Herring, Petrucci, 2002). Although copper may seem necessary, greater quantities of this substance can be deadly (Hardwood, Herring, Petrucci, 2002). Copper can combine with various substances, resulting in several copper compounds. This experiment demonstrates such syntheses and can be represented by: Cu „³ Cu(NO3)2 „³ Cu(OH)2 „³ CuO „³ CuSO4 5H2O „³ Cu The copper begins as a wire until it has undergone several reactions, where it is eventually isolated as a pure substance. All the initial copper is nearly all recovered, as the experiment was done avoiding any spilling or leaving the product on the sides of the apparatus. The percent yield is then calculated from the initial copper wire and the resulting mass of copper. As soon as HNO3 was added to the copper, the cop...
