S = Sproducts - Sreactants. Interpreting non-statistically significant results: Do we have "no evidence" or "insufficient evidence" to reject the null? You might well be correct, but energetically to lose four strongly bound waters before losing one other one does not seem to be what one would expect. Compound states [like (s) (aq) or (g)] are not required. Students can then see the copper disappearing from the surface of the copper-coated anode: the anode consists of an unrefined sample of the metal; the cathode is made of pure copper or a support metal such as stainless steel.
