the job). At first, nothing happens. Add a spatula of CuSO4.5H2O to this. A REALLY violent reaction starts at once, giving a lot of steam! So, the H(+) ions help, but the Cu(2+) still is required. Now do the same experiment with dilute H2SO4 (e.g. 10%) and add some copper sulfate. Now the violent reaction does not occur! Only after
