A Redox Reaction Using Copper and Zinc (animation)

In this demonstration, dissolved copper ions come in contact with zinc, and zinc gives up its electrons to the copper. Zinc loses two of its electrons, becomes ionized +2, and its ions move into the solution. At the same time, because the copper ions gain two electrons, they become neutral copper metal, which is deposited on the surface of the zinc.
