Dissimilar metals and alloys have different electrode potentials, and when two or more come into contact in an electrolyte, one metal (that's more reactive) acts as anode and the other (that's less reactive) as cathode. The electropotential difference between the reactions at the two electrodes is the driving force for an accelerated attack on the anode metal, which dissolves into the electrolyte. This leads to the metal at the anode corroding more quickly than it otherwise would … WebJun 16, 2024 · Rising of a corpse galvanized by a primitive galvanic battery. Giovanni Aldini placed electrodes on Foster’s face and connected them to a large battery. When Aldini threw the switch, “the jaws of the deceased criminal began to quiver, and the adjoining muscles were horribly contorted, and one eye was actually opened.”
