Chemistry Music Video 27: You Start At The Anode

This song describes the workings of a voltaic cell, tracing the path of negative charge (external circuit: electrons through the wire, internal circuit: anions through the salt bridge). All music and lyrics copyright 2005 by Mark Rosengarten. All rights reserved. Lyrics: Vital to make a battery Is this electrochemistry You take two half-cells And connect them up so well With a load to power in between You need to have electrodes, you see Full of that metallicity Let electrons flow Across the salt bridge we go! Allowing us to make electricity We start at the anode Electrons are lost there And go through the wire (And through the load on fire) They enter the cathode And reduce the cations And the anions go through the salt bridge back to where? Where? (Repeat this six more times and end with) The anode!!!
