Blue Bottle, Red and Blue Bottle  
Color changes are caused by reactions of oxygen in the air with chemicals in a solution. The colors fade over time, but can be regenerated by shaking the flask containing the solution.

Induction by Iron(II) of the Oxidation of Iodide by Dichromate  
Acidic aqueous solutions containing dichromate and iodide ions are mixed with no reaction. The addition of a solution of iron(II) ion induces the rapid formation of brown triiodide ion.

Kinetics : IntermediateInMech (15 Variations)
Suppose that for the reaction of nitrogen dioxide and carbon monoxide
NO2 + CO NO + CO2

the following mechanism has been proposed at high temperatures:
(1) NO2 + CO O-N-O-C-O (slow)
(2) O-N-O-C-O NO + CO2 (fast)
Check the box for each species that is an intermediate in this mechanism.

Synthesis Explorer: A Chemical Reaction Tutorial System for Organic Synthesis Design and Mechanism Prediction  Jonathan H. Chen and Pierre Baldi
Synthesis Explorer is an interactive tutorial system for organic chemistry that enables students to learn chemical reactions in ways previously unrealized. Pedagogical experiments in undergraduate classes at UC Irvine indicate that the system can improve average student examination performance by ~10%.

Saying What You Mean: Teaching Mechanisms in Organic Chemistry  J. Brent Friesen
Ways to maintain clarity and consistency when teaching reaction mechanisms in organic chemistry include the use of balanced reaction equations, avoiding the use of shortcut notations, including key electrons and bonds in structural representations, and distinguishing between covalent and ionic bonds.

Teaching Reaction Mechanisms Using the Curved Arrow Neglect (CAN) Method  John H. Penn and Abdulrahman G. Al-Shammari
A new method for teaching organic reaction mechanisms that concentrates on intermediate reaction structures and can be used in a computer-assisted instruction environment is found to significantly enhance student performance in drawing traditional reaction mechanisms.

Mechanism-Based Kinetics Simulator  Robert M. Hanson
Simulate the kinetics of a reaction based on its mechanism using JavaScript. The idea is to write a mechanism and, based on that, follow the course of concentrations or rates of change in concentration of reactants, catalysts, intermediates, and products over time.

Mechanisms That Interchange Axial and Equatorial Atoms in Fluxional Processes  Marion E. Cass, Henry S. Rzepa, King Kuok Hii
The Berry pseudorotation is a classical mechanism for interchanging axial and equatorial ligands in molecules with trigonal bipyramidal geometry. Teaching this mechanism presents particular pedagogic problems due to both its dynamic and three dimensional character. The approach taken here illustrates these processes using interactive animations embedded in a Web page and overcomes many limitations of a printed page.
