Oxidation–Reduction
Foiled Again—Aluminum Loses to Copper
By: The Flinn Staff
Students observe color changes, production
of a gas, formation of a solid and a drastic
change in temperature. Students learn the
crucial role of a catalyst with this visually
dramatic demonstration—a true redox battle
between aluminum and copper.
Concepts: Oxidation–reduction, catalysis,
single replacement reactions.

AP5936 Foiled Again—Aluminum Loses to Copper—
Chemical Demonstration Kit
$46.75
Colorful Electrolysis
By: Mike Shaw, West Stokes High H.S., King, NC
A 9V battery supplies the power and universal indicator
provides the color show. As electrolysis occurs in
the Petri dish, the pH changes at the anode and cathode
are different. The entire spectrum of universal
color changes occurs, reflecting the pH continuum
created in the Petri dish.
Concepts: Electrolysis, pH.

CHEMICAL DEMONSTRATION KITS—OXIDATION–REDUCTION continued on next page.
The Peddie School, Hightstown, NJ
When you add a small amount of glycerin to potassium
permanganate, your students will witness the oxidation of
glycerin by a permanganate. The reaction is very dramatic!
Concepts: Oxidation–reduction, exothermic reactions.
Note: Perform this demonstration in a fume hood or
well-ventilated lab.

AP2087 Rapid Oxidation—Chemical Demonstration Kit $20.90
Feeling Blue
By: Jim and Julie Ealy, Retired,
The Peddie School, Hightstown, NJ
Two colorless solutions and an indicator
are mixed, producing a blue solution. Upon
standing, the solution becomes colorless. The
solution alternates between blue and colorless
with shaking and standing, respectively.
Concepts: Oxidation–reduction, indicators, kinetics.

Stop-’N-Go Light
By: Jim and Julie Ealy, Retired,
The Peddie School, Hightstown, NJ
When you shake this flask of solution, the color of
the solution will turn from a soft yellow to a bright
red to a light, grassy green and then shift back to
yellow again.
Concepts: Oxidation–reduction, indicators, kinetics.

The Reversible Orange
and Blue Reaction
By: Marie Sherman and Dr. Deborah Weil,
Ursuline Academy, St. Louis, MO
A warm, clear, blue solution starts to bubble, the
temperature rises, the bubbling becomes vigorous and
suddenly the solution becomes an opaque orange-gold
color. Since the reaction is reversible, you can repeat it
several times.
Concepts: Oxidation–reduction, complex ions.

AP8684 The Reversible Orange and Blue Reaction—
Chemical Demonstration Kit
$35.30
Reversible Tin Man
By: The Flinn Staff
Students will enjoy watching tin crystals grow
before their very eyes across a Petri dish and
then quickly “reverse” as the cathode and
anode are switched.
Concepts: Electrolysis, oxidation–reduction,
anode, cathode.

Writing with Electricity
By: Paul Price, Trinity Valley
School, Fort Worth, Texas
Demonstrate the key concepts of
electrochemistry, including anodic
and cathodic reactions, by using a
copper “pen” to follow the flow of
electrons in the electrolysis of aqueous
potassium iodide.
Concepts: Electrochemistry, acid–
base indicators.

The Electrochemical Clock Kit—
Irwin Talesnick’s Orange Juice Clock
By: Irwin Talesnick, Chemistry Dept.,
Retired, Queens University, Kingston,
Ontario, Canada
Arouse student curiosity. How does the clock
work? How long will the clock run on orange
juice? Can you use something other than orange
juice?
Concepts: Electrolysis, oxidation–reduction,
anode, cathode.
Note: A stiff piece of cardboard or wood for
hanging the clock is required.
