Document Summary

Reduction-oxidation reactions (redox: the oxidation numbers of atoms may change over the course of a reaction from reactants to products, and when they do, we say a redox reaction took place. If 2 half reactions occur in the same vessel, it is difficult to harness the energy. If we keep the 2 half reactions separated yet connected electrically by a salt bridge and an external wire, we can create an electrochemical cell. Standard electrode potentials: the problem in measuring electrode potentials is that absolute half-cell potentials can"t be measured. The oxidation os zinc by cu2+ has a higher tendency to go to completing the more positive, the more tendency there is to go to completion. Relationship between e cell and g : ecell- an electromotive force which has a capacity to do work, welec = zfelec (amount of e- that can be extracted from a chemical process and can therefore be equal to g.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. Oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. In general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number.

An oxidizing agent is an element or compound in a redox reaction that oxidizes another species and itself gets reduced and is therefore the electron acceptor in the reaction.

A reducing agent is an element or compound in a redox reaction that reduces another species and itself gets oxidized and is therefore the electron donor in the reaction.

As a summary, keep in mind the following:
