And zinc solid becomes zinc in the Aqueous state with a plus two charge, and it releases two electrons while in half cell number two reduction occurs. An aqueous copper takes up two electrons to form solid copper. So let's examine these reactions as they occur within our electrochemical cell, our voltaic cell. So in eco number one and half cell number one, this red bar corresponds to our zinc solid. So zinc solid releases two electrons and it also releases our zinc ion. Now, this zinc ion is released into our solution from our metal bar.
