Are you feeling the reduction-oxidation?
I took my
car back
to the
dealer,
said “This
thing is
almost
new!”

“Just take
a look at
that
fender—
it’s almost rusted through!”
He said
“You got
REDOX,
baby,
eating at
your car!”
Redox 
You better do something
quick…
…before that process goes
too far.
Redox
ItThat’s
meansa reduction-oxidation.

Now oxidation is a
loss of electrons
eee- e-e- eeeeee-e- e- And
reduction
is a gain
Now oxidation is a

eee- e-e- eeeeee-e- e- And
reduction

But that’s just the
beginning…
You see,
oxidation and
reduction
always happen
as a pair.
…There’s lots
more to explain
Oxidation and
reduction always
happen as a pair
If you got oxidation,
reduction must be there

You see, it’s more
than just corrosion,
when metals
Redox
= meet
the air.
It’s more than just
+ corrosion, when
metals meet
the air.
Redox happens when
you burn a match

Or even bleach
your hair
So get the rust off
that car and paint it.
And put on a
happy face
Get the rust off that

Until you seal it from the air
REDOX will still take place
