Reaction Tendencies
 This program introduces Le Chatelier's principle: if a system in equilibrium is subject to stress, the system tends to react in such a way as to oppose the effect of the stress. It examines this principle by observing the effects of two types of stre...(more details) |

The Building Blocks of Electrochemistry
 Basic concepts of electrochemistry are introduced with the aid of a robot powered by an electrochemical cell. The chemical reactions that occur inside the cell demonstrate the principles of reduction and oxidation-the redox reactions-that produce the...(more details) |

Corrosion
 This program investigates why rust develops. The oxidation-reduction reaction that produces corrosion is shown, explaining the role of the electrochemical cell. Ways to prevent and control corrosion by galvanization and cathodic protection are illust...(more details) |

Electroplating
 The causes and results of electrolysis, a nonspontaneous reaction requiring a source of electrical energy, are shown through animation. We discover that studying the reduction potentials for each possible half-cell reaction enables us to predict whic...(more details) |

Designing Electrochemical Cells
 This program shows how to build a super electrochemical cell, explaining the need for a standard half cell, how to predict the direction of the electron flow, and, finally, how a table of reduction potentials can predict the output of a cell. (10 min...(more details) |
