Redox Electron Transfer and Half-Reactions

Redox reactions involve the transfer of electrons from one species to another. In this type of reaction, electrons are not shared between atoms. They move from the species that loses them to the species that gains them.

The species that loses electrons is the reducing agent, also called the reduc...

An Oxidation-reduction or redox reaction involves the transfer of electrons from the reducing agent to the oxidizing agent.

Species that undergo an increase in their oxidation state are oxidized, while those that experience a decrease in their oxidation state are reduced.

So, the thermodynamics of the redox reaction is expressed in...
