In class, we make a wet cell consisting of a zinc electrode and a 
copper electrode immersed in a beaker of copper sulfate (Both electrodes 
are in the same solution).A light bulb is connected between the two 
electrodes in order to detect a current.  Although I am aware of most 
of the chemistry going on in the cell, there are gaps, especially as 
to what is happening at the copper electrode. Can you enlighten me and 
explain as much of the chemistry going on in the cell as you can?  
Please include electron movement, ion movement, and complete chemical 
reactions if possible.
