AP7155 - $31.45
A rainbow spectrum of color changes provides visual proof of the effect of a catalyst. Hydrogen peroxide is added to two separate flasks, each containing a basic solution of sodium thiosulfate, along with universal indicator. One flask also contains...
AP2084 - $26.40
Learn how a catalyst works by observing the color changes of pink cobalt ions. You'll see the catalyst as it gets swept up in the oxidation of tartrate by hydrogen peroxide, changes into a green intermediate, and then reappears again at the end. A...
AP8657 - $27.45
In a flash, like magic, a colorless solution turns a dramatic dark blue color. You and your students will be amazed by this popular starch-iodine clock reaction. Teacher Demonstration Notes included. Enough materials are provided to perform the demonstration...
AP2092 - $32.51
When sodium iodide is dropped into a flask containing 30% hydrogen peroxide, a “magical” genie appears in the form of water vapor and oxygen. Teacher Demonstration Notes included. Enough materials are provided to perform the demonstration seven times.   Concepts:...
AP4601 - $46.40
Mix two colorless solutions and watch as, after a few seconds, they suddenly change from colorless to dark blue. What an attention-getter! This kit allows you to quantitatively demonstrate the popular iodine-starch clock reaction. In each demonstration,...
AP2085 - $25.41
This will be your students' favorite chemical reaction! Mix a combination of chemicals together with dishwashing liquid in a tall borosilicate cylinder and stand back. Watch as a large amount of soapy foam erupts from the cylinder. The catalyzed decomposition...
AP4866 - $65.01
Teach kinetics in a fun and sudsy way! This three-part demonstration provides an interesting twist on the traditional “Old Foamey” demonstration. Show your students the effect of concentration on reaction rate, observe a reaction intermediate and test...
AP6603 - $118.85
It's spring break. Time to cast off the winter doldrums and embrace the bright new season! Celebrate the arrival of spring with six fun demonstrations: • An oscillating chemical reaction alternates between frigid blue and sunny yellow, just like the...
AP7421 - $63.35
Try this amazing demonstration! Construct a model volcano using polyurethane foam, and then produce a fiery lava flow using the decomposition of hydrogen peroxide and light stick chemicals. An awesome display of chemical reactions simulating a volcanic...
