False Oxidation occurs at the cathode of a galvanic cell, but at the anode of an electrolytic cell. False A salt bridge provides a path for the electrons to move between the anode and cathode compartments of a voltaic cell. False
In 1780, Luigi Galvani discovered that when two different metals (e.g., copper and zinc) are in contact and then both are touched at the same time to two different parts of a muscle of a frog leg, to close the circuit, the frog's leg contracts. He called this "animal electricity". The frog's leg, as well as being a detector of electrical current, was also the electrolyte (to use the language of modern chemistry).
