Explains why corrosion is a major concern of industry and consumers. Shows various everyday examples of corrosion reactions and how they can be prevented. The five-step method for writing these reactions is used throughout the program.

Explains Le Châtelier’s principle and shows how his work is used to identify factors that can affect equilibrium concentrations. Demonstrates how equilibrium can be shifted by changing temperature or the concentrations of various reagents.

Emphasizes the usefulness of redox titration as an analytical technique. Examines titration procedures and techniques and explains how to determine the endpoint of a redox titration.

Shows the complete cycle of a redox titration. Analysis of the data covers: predicting the endpoint colour change; standardizing the titrant; titrating the unknown; and stoichiometric analysis of the data.

Detailed graphics explain oxidation numbers within molecules and complex ions. Examples show the rules for assigning oxidation numbers and for writing half-reactions using oxidation numbers.

Explains enthalpy changes in terms of rearrangement of chemical bonds and examines how to graphically determine enthalpy change for a reaction using known enthalpy changes for other reactions.

Shows how enthalpy changes can be communicated: as a term in an equation; as a delta H or molar delta H notation; and as a potential energy diagram. Demonstrates Hess’s Law using calorimetry, potential energy diagrams and molar enthalpies of formation.

Determines the molar enthalpy of neutralization of sodium hydroxide using calorimetry. The experimental value is then compared to the actual value that was determined using Hess’s Law.

Provides additional information, experiments and problems on concepts presented in the video programs.
