standard electrode potential

Standard electrode potentials are available in a table of values.

An extract from the table of standard electrode potentials is shown below.

Then one looks up the standard electrode potential, E, in volts, for each of the two half reactions.

This method of calibration avoids the need to know the standard electrode potential.

The standard electrode potential is the tendency of a bulk material to draw free electrons to itself.

We have thus related the standard electrode potential and the equilibrium constant of a redox reaction.

The standard electrode potential for the SHE is zero, by definition.

Therefore, standard electrode potential is commonly written as standard reduction potential.

The sulfate radical formed in situ has a standard electrode potential of 2.7 V.

Titanium has many different standard electrode potentials depending on the oxidation state it is in.

Notation for half-reaction standard electrode potentials is as follows.

The standard electrode potential for this compound is +1.44 V with a half reaction generating the hydrogen sulfate.

A number of standard electrode potentials, depending on the reaction under study, are reported for indium:

To allow prediction of the cell potential, tabulations of standard electrode potential are available.

As the standard electrode potential is more negative the aqua ion is more difficult to reduce.

For example, the standard electrode potential for a copper electrode is:

Changes in the stoichiometric coefficients of a balanced cell equation will not change E value because the standard electrode potential is an intensive property.

Standard electrode potentials are usually tabulated as reduction potentials.

Replies: Dear Neda, There is no relationship between electronegativity and standard electrode potential.

(See table of standard electrode potentials).

Using standard electrode potentials in this way must be done with caution as factors such as complex formation and solvation may affect the reaction.

Electrochemical series, a method in chemistry of listing ions in order of standard electrode potential (data page)

With a standard electrode potential (SEP) of 0.76 volts, zinc is used as an anode material for batteries.

Standard electrode potentials offer a quantitative measure of the power of a reducing agent, rather than the qualitative considerations of other reactivity series.
