Chemistry Music Video 27: You Start At The Anode

Details

Description

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!!!
