If Molecules Were People...
By watching this droll and delightful animation, physical scientists consider what happens when molecules collide. In this film, however, parodic people bump into each other, exchanging limbs in the process, just as molecules might trade individual atoms!

Chemistry Lab: Chemical Equilibrium
Students investigate the effects of adding or removing a reactant or a product on chemical equilibrium. In this equilibrium lesson plan, students add or remove ions to solutions to determine the effects on equilibrium. They make observations of color changes in the solutions to determine equilibrium.

Spectrophotometer Determination of an Equilibrium Constant
Students determine an equilibrium constant using a spectrophotometer. In this equilibrium lesson plan, students calibrate a spectrophotometer with 5 solutions in order to prepare the spectrophotometer for the experiment. Students measure the absorbance of the solutions in order to determine the concentration of ions and the equilibrium constant for the equation.

Aquarium Equilibrium Demonstration
Sometimes equilibrium is a difficult concept for a beginning chemist to grasp. Here is a demonstration that helps them to visualize what is happening at a molecular level. Using two aquariums and different sizes of beakers to transfer water back and forth between them, observers can see when equilibrium is reached.

Reactions in Equilibrium
Equilibrium constants are the focus of this chemistry video. Sal demonstrates that once the equilibrium constant has been established for a chemical reaction, one can change the concentrations of the reactants and predict what the resulting concentrations are going to be ( after the reaction has taken place.

Sal explains what happens when compounds that are in different states, (solid, liquid, gas), are in a chemical reaction with each other. Through the use of diagrams, Sal demonstrates how compounds of different states attempt to achieve heterogeneous equilibrium with each other during the chemical reaction.
