amazing...

Just look at this flower...it mimics a bee beautifully! Isn't biology wonderful?...

Quantitative redox chemistry

The understanding and application of electrode potentials allows us to do one of two things: Build cells or predict the likelihood of a redox equation. In building cells two couples are required with different values of redox potential. One couple...

Absolute electrode potentials

Although it is not difficult to measure relative half-cell potentials, it is impossible to determine absolute half-cell potentials because all voltage measuring devices measure only differences in potential. To measure the potential of an electrode, one contact of a voltmeter...

Building cells....

Using redox chemistry as a source of mobile electrical energy is inspired! I mean..without this you'd NEVER be able to say "I'm on the train...!". Two half equations with different E^o values is all that it takes. Thes can be...

Predicting Redox Reactions

This is a further use to which a table of redox potentials may be put. To do this you need to adopt a specific protocol, which once mastered is easy to follow. Start by reading the question carefully and combine...

Building cells...

Two couples with different electrode potentials may be combined to build a cell, a device to physically separate the oxidation from the reduction so that when the electrons move from one process to the other they pass through the external...
