"the standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials."
The standard hydrogen electrode is a reference electrode used to measure the standard electrode potentials of other half-cells.
Oxidation-Reduction Reactions: These are chemical reactions where one substance loses electrons (oxidation) and another gains electrons (reduction).
Electrochemical Cells: These are devices that convert chemical energy to electrical energy or vice versa.
Half-reactions: These are the two parts of a redox reaction, where electrons are transferred from one species to another.
Electrode Potential: It is the voltage that develops across an electrode when it is placed in a solution with which it can react.
Galvanic Cell: It's a voltaic cell where a spontaneous redox reaction drives an electric current through an external circuit.
Electrolytic Cell: It's a cell where an external source of current is used to drive a non-spontaneous redox reaction.
Standard Reduction Potential: It's the potential difference, measured under standard conditions, between the reduction half-reaction and the standard hydrogen electrode.
Nernst Equation: It's an equation that relates the electrode potential of a half-cell to the concentration of its constitutive species.
Cell Potential: It's the difference in electrode potentials between the anode and cathode of a galvanic cell.
Standard Electrode Potential: It's the potential difference, measured under standard conditions, between a half-cell and the standard hydrogen electrode.
Concentration Cells: It's a type of galvanic cell where the concentration of one species in each half-cell differs.
Overpotential: It's the additional potential required to overcome the activation energy of an electrochemical reaction.
Activity Coefficient: It's a measure of how much the concentration of an ion deviates from ideal behavior.
Corrosion: It's the destructive attack of a metal by chemical or electrochemical reaction with its environment.
Electrodeposition: It's the process of depositing a metal ion onto an electrode surface by electrolysis.
Fuel Cells: It's a device that converts the chemical energy of a fuel directly into electrical energy by an electrochemical reaction.
Bioelectrochemistry: It's the study of the electrical properties of biological systems, including the electrochemical behavior of proteins and enzymes.
Analytical Electrochemistry: It's the application of electrochemical techniques to the measurement of chemical species in solution.
