Experiment+12

Has anyone started the analysis questions or see any patterns in the data? I don't know if it's a coincidence, but every time a solid formed, Pb(NO3)2 was one of the reactants.

The combination of CuSo4 and AgNO3 was missing. The Reaction is CuSO4 (aq) + 2AgNO3 (aq) => Ag2SO4 (s) + Cu(NO3)2 (aq) Also, NaOH and HCl combine to create HOH (aq) and NaCl (aq). Because both look identical, it would be impossible to see this reaction. The same is true for the reaction between ZnSO4 and 2AgNO3, which yield Ag2SO4 (aq) and Zn(NO3)2 (aq). Also I see a pattern emerging in that nothing with a Chlorine ion could react with anything with a SO4 ion. This makes it likely that in the table below, ZnSO4 and HCl don't react. this is interesting, because in all of the cases where a SO4 is combined with HCl, the chemical formula states that the product would be H2SO4 - sulfuric acid. HCl is also hydrochloric acid, and I wonder if their acidity compared to each other has something to do with the lack of a reaction (or at least a visible one). ---Aaron

Aaron- What you said about the Cl and SO4 is true, but there were no reactions with cases that didn't involve those 2. So there has to be some other kind of pattern as well.

-Miriam This is our data plus all the balanced chemical reactions. I don't know how accurate they are but I got almost all of them from http://www.webqc.org/balance.php. The first file didn't open for some people so I tried exporting it, so hopefully the second one works.
