standard hydrogen electrode

Most of its characteristics are similar to the standard hydrogen electrode (with platinum).

For this reason, standard hydrogen electrode is typically used for reference potential.

Common reference electrodes and potential with respect to the standard hydrogen electrode:

From the above, for the cell with the standard hydrogen electrode (potential of 0 by convention), one obtains:

Finally the column potential indicates the electric potential of the element measured against a Standard hydrogen electrode.

Potentials of any other electrodes are compared with that of the standard hydrogen electrode at the same temperature.

The scheme of the standard hydrogen electrode:

Such tabulations are referenced to the standard hydrogen electrode (SHE).

The hydrogen-ion selective electrode is a standard hydrogen electrode.

(SHE) denotes the electrode potential relative to the standard hydrogen electrode.

Reference electrode (standard hydrogen electrode or an equivalent)

The standard hydrogen electrode also uses a platinized platinum electrode due to its corrosion resistance, and other attributes.

A reference electrode, standard hydrogen electrode (SHE), for which the potential is defined or agreed upon by convention, needed to be established.

The potential of a copper copper sulfate electrode is +0.314 volt with respect to the standard hydrogen electrode.

These half-cell potentials are derived from the assignment of 0 volts to the standard hydrogen electrode (SHE).

For example, hydrogen is oxidized and protons are reduced readily at the platinum surface of a standard hydrogen electrode in aqueous solution.

The standard electrode potential E against standard hydrogen electrode (SHE) is 0.230V 10mV.

The potential of a silver:silver chloride reference electrode with respect to the standard hydrogen electrode depends on the electrolyte composition.

Liquid mercury is a part of popular secondary reference electrode (called the calomel electrode) in electrochemistry as an alternative to the standard hydrogen electrode.

The vertical axis is labeled E for the voltage potential with respect to the standard hydrogen electrode (SHE) as calculated by the Nernst equation.

The standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials.

Relationship between the normal hydrogen electrode (NHE) and the standard hydrogen electrode (SHE)

The standard reduction potential is defined relative to a standard hydrogen electrode (SHE) reference electrode, which is arbitrarily given a potential of 0.00 volts.

Surface polarization interferes with measurements, but various sources give an estimated potential for the standard hydrogen electrode of 4.4 V to 4.6 V (the electrolyte being positive.)

Group 12 elements are also used in electrochemistry as they may act as an alternative to the standard hydrogen electrode in addition to being a secondary reference electrode.
