      Describe and explain galvanic in terms of oxidation/reduction reactions. In 1791, Luigi Galvani investigated the connected between metals and electricity using frog muscles. He observed that if two different metals were inserted into frog leg muscle, an electric current was generated.

      Back in the late 1700’s, Luigi Galvani observed that the electrochemical behavior of two dissimilar metals [(zinc (Z) and copper (Cu)] in a bimetallic arch, in contact with the electrolytes of tissue, produces an electric stimulating current that elicits muscular contraction.

      The Galvanic Series(a ranking of metals and alloys as to their relative electrochemical reactivity in seawater. Essentially all metals occur in nature as compounds. Exceptions are gold and platinum because, for them, oxidation in most environments is not favorable, and, therefore, they may exist in nature in the metallic state. Corrosion Rates

      Galvanic Corrosion. Galvanic corrosion results from two different metals being in contact in the environment. Examples would be brass plumbing fittings on a cast iron pipe.

      This hierarchy is called a Galvanic series, and can be a very useful in predicting and understanding corrosion. 5. Resistance to corrosion. Some metals are more intrinsically resistant to corrosion than others, either due to the fundamental nature of the electrochemical processes involved or due to the details of how reaction products form.
