From what this site told me, the reason that the salt and vinegar combination is the one that cleans the pennies is that in the exact words “ When the salt and the vinegar are mixed together, the salt dissolves in the vinegar solution and breaks down into sodium and chloride ions. The chloride ions then combine with the copper in the penny to remove the tarnish or copper oxide from the surface of the penny ” ( qtd. in Spangler, Steve //Naked Eggs and Flying Potatoes // p.g. 61-65 ).

The information about the combination of salt and vinegar being able to clean the tarnish off of pennies, which was my hypothesis, was information discovered over the course of the experiment, but the exact process happening in the chemical reaction and why the chemical reaction was occurring was some new and very interesting pieces of information that i would have never thought of.
