This song describes the process of electrolytically decomposing a fused salt as well as water. All music and lyrics copyright 2005 by Mark Rosengarten. All rights reserved.

Lyrics:

If you got a compound
That you need to break apart
Just use electric current
Electrolysis is smart!

I need to make some chlorine
And put it in my pool
Ill invite my buddies over
Theyll think Im really cool!

But where can I get chlorine
Its in Group Seventeen
Its only found in compounds
Its toxic and its green!

But then I found some salt
Made of Na and Cl
I heated it till it melted
Cause liquid motions swell

The ions separate
When ionic bonds are broke
Theyre free to move around
Like the liquid that I spoke

I put electrodes in
Connected to D.C.
The ions moved towards them
Because of charge, you see

The sodium got electrons
From the cathode side
And reduced to metal Na
There is nowhere to hide!

The chloride lose electrons
At the anode are they lost
The chlorine gas then bubbles
Into the pool its tossed!

Now my buds come over
My social life cant miss!
They think Im really cool
Thank you, electrolysis!




If you got a compound
That you need to break apart
Just use electric current
Electrolysis is smart!

I need to make some hydrogen
But it is in Group One
I want to make a fuel cell
To make my gadgets run!

All I need is water
It has the H I need
Ill put it in a beaker
Invert test tubes with speed

Waters not an electrolyte
(Which means it wont conduct)
Ill add sulfuric acid
And then Ill have some luck!

Electrodes hooked up to D.C.
Are placed into the mix
Electricity is turned on
My situations fixed!

The H+ ion gets reduced
At the negative cathode
And forms some H2 gas
Its volume quickly growed!

Oxygen gets oxidized
At the anode positive!
Oxygens the gas
That we need to live!

Now I have my H2 gas
That powers my fuel cell
I can listen to my music
Electrolysis is swell!

You can do the same
To get lots of elements
This goshdarn electrolysis
Just makes a lot of sense!
