|
Oxidation State
|
Equal to the charge of an ion or to the charge an atom would have if the compounds were ionic, represents the degree of oxidation of an element.
|
|
|
Reduction
|
Loss of electrons, process in which the oxidation state of an element decreases.
|
|
|
Oxidation
|
Gain of electrons, process in which the oxidation state increases
|
|
|
Disporportionate Reaction
|
A reaction in which a substance undergoes both oxidation and reduction.
|
|
|
Oxidizing/Reducing Agent
|
an element whose oxidation state increases/decreases; gain/loss of electrons.
|
|
|
Electrode Potential
|
Measure of electric charge density on an electrode where oxidation/reduction occurs
|
|
|
Anode
|
Electrode where oxidation occurs
|
|
|
Cathode
|
Electrode where reduction occurs
|
|
|
Galvanic cell
|
Electrochemical cell that produces electricity as a result of a spontaneous reaction.
|
|
|
Free Energy
|
Portion of total energy that can be used for work.

|
|
Entropy
|
Degree of disorder within a system.
|
|
|
Enthalpy
|
Amount of internal energy in a system capable of doing work.
|
|
|
Corrosion
|
Deterioration of a substance through unwanted oxidation
|
|
|
Sacrificial Anode
|
the active metal in cathodic protection, one being oxidized.
|
|
|
Cathodic Protection
|
Process of coating an active metal such as magnesium to an object in order to protect it from oxidation
|
|
|
Electrolysis
|
Forcing of a non-spontaneous reaction to occur.
