Why might a galvanic cell go dead? Socratic

The main reason is that the anode gets "used up," or depletes. This is a galvanic cell: The two main components of a galvanic cell is the anode, which sends electrons, and the cathode, which receives these electrons. In order for the galvanic cell to do work/not be dead, this flow of electrons through the wire, from the anode to the cathode, needs to be maintained. In our diagram, the zinc ...
