EQUILIBRIUM
Exploring Equilibrium:
It Works Both Ways—
Student Laboratory Kit
Students explore the nature and conse- quences of equilibrium in three reversible chemical reactions—the acid–base equi- librium of bromcresol green indicator,
the solubility equilibrium of magnesium hydroxide and the complex-ion equilibrium of iron(III) thiocyanate. Students practice critical-thinking skills as they apply their knowledge to predict whether a reaction is exothermic or endothermic. Complete for 30 students working in pairs.

The Wacky World of Superabsorbent Polymers— Chemical Demonstration Kit
Pour distilled water into an “empty” cup and the water solidifies into a gel. In a beaker add a small amount of powder, pour in distilled water and see an avalanche of fresh powdered “snow.” These sodium polyacry- late polymers have many applications. AP6303 | $17.05
Characteristics of Chemical
Restoring Balance—Le Chatelier’s Principle and Equilibrium— Student Laboratory Kit
Equilibrium is a true chemical balancing act. In this classic chemistry experiment, students examine how concentration and temperature affect the sensitive “pink-and-blue” balance in the complex-ion equilibrium of cobalt chloride in water. Students predict changes based on Le Chatelier’s Principle and see the colorful effects in action. Let your students see for themselves the true nature of chemi- cal equilibrium!

Equilibrium—Activity-Stations Kit
Chemical equilibrium is a balancing act—what happens when the balance
is disturbed? In this activity-stations lab, students investigate various reaction condi- tions that may influence that balance. Four “mini-lab” activities are set up. Each activity focuses on a specific property of chemical equilibrium. Includes Teacher Notes with real sample data, background information, student handouts and all necessary supplies.

Mystery Nylon Factory—
Polyurethane Foam System—
Chemical Demonstration Kit
When these substances are mixed, a rigid foam is produced. The volume of foam produced is 20–30 times larger than the orig- inal mixture. Experience the excitement of polyurethane foam!

Chemical Demonstration Kit
Two solutions are poured together in a beaker. A paper clip is lowered into the solu- tion. As the paper clip is withdrawn, almost by magic a very long strand of nylon is pulled from the beaker. A super demonstra- tion to discuss polymer concepts. Teacher Demonstration Notes included.
