II. Voltaic cells (Batteries)<br />

A. Theory of operation<br />

Zn(s) + Cu +2 (aq) fi Zn +2 (aq) + Cu(s)<br />

This does not look like a battery because the electrons are<br />

being transferred directly between Cu +2 and the Zn strip.<br />

If we separate the reactions and force the electrons to<br />

travel through a circuit we could use these electrons as<br />

they try to get from the Zn to the Cu +2 .<br />
