The redox reactions that go into determining the ORP are usually electron transfers. For example, the reaction of ferric ion (Fe) with copper metal (Cu):
What Redox Reactions Control the ORP in Seawater and Marine Aquaria?
As if simply asking "What is the ORP of natural seawater?" was not complicated enough, try asking why the ocean has the ORP that it does. In the parlance of the redox war described above, this question equates to asking "Who is really fighting on the front lines of the war, and why does it end up in the particular steady state that it does?" The answer is very complicated, and many aspects of this discussion will be detailed more fully in the more scientific explanations to follow. Nevertheless, these guiding factors are worth considering:
Likewise for redox reactions, a steady state of electron pushing and pulling is reached, and that state can be represented by ORP. The analogy breaks down, however, because not all oxidizers and reducers are capable of reacting with each other (or the ORP probe) in a short period of time. Given enough time, for example, oxygen (as the oxidizer) will react with ethanol (the reducer) to form a variety of products, ultimately ending in carbon dioxide and water. That reaction is very slow, however, and might not happen at all over the lifetime of a reef aquarium.

What causes the overall process to be unidirectional? To understand this, we will have to say a bit more about redox reactions and irreversibility.
The Balanced Chemical Equation for Photosynthesis?
Oxidation-reduction reactions ("redox reactions") involve electron transfers between reactants and, in the process, the oxidation states of atoms in those reactants change. One atom might lose one or more electrons and become oxidized, which the other will gain one or more electrons and become reduced. A balanced equation of the overall process assures that an equal number of electrons are lost and gained.

It is easier to understand what happens in this reaction, however, if we assignoxidation numbers to each of the carbon atoms in the Lewis structures of the components ofthis reaction, as shown in the figure below.
