WebThe electrode of an oxidation cell is called the anode. In this example the anode is zinc. As the reaction occurs, electrons leave the zinc metal in the anode, converting it to zinc ions. These ions then enter the solution, in this case zinc sulfate. The counterion doesn’t matter, as long as it’s soluble with the anode metal ion. WebMay 4, 2015 · So, to answer your 2 main concerns, think of a voltaic cell as a electric circuit: In one half cell, we have a S n anode in water connected to a wire. Water is not a good conductor of electricity, dissolved ions are needed, such as the S n X 2 + ions are needed to facilitate the movement of the electric current in the first place.
