standard potential

All missing elements in this table are either not metals or have a negative standard potential.

The standard potential of the water electrolysis cell is 1.23 V at 25 C.

The half cell standard potential is given by:

The standard potential of this electrochemical reaction is:

The standard potential of an electrochemical cell requires standard conditions for all of the reactants.

In order to calculate the standard potential one looks up copper and zinc's half reactions and finds:

The standard electrical potential of a cell can be determined by use of a standard potential table for the two half cells involved.

The standard potential Am/Am is 2.08 0.01 V.

The species are connected by an arrow, and the numerical value of the standard potential (in volts) for the reduction is written over the arrow.

The value of the half-wave potential is related to the standard potential for the redox reaction being studied.

When reactant concentrations differ from standard conditions, the cell potential will deviate from the standard potential.

The standard potential for the cell is equal to the more positive E value minus the more negative E value.

Disadvantages include the need for procedures on the woman, and the standard potential side-effects of IVF for both the mother and the child.

A consequence of the temperature dependency of standard potentials is that the voltage produced by a galvanic cell is also temperature dependent.

Figure 1 shows the standard potentials at pH 0 (strongly acidic) as referenced to the normal hydrogen electrode (NHE).

Bard et al. give the following correlations for the standard potential of the silver chloride electrode as a function of temperature (where t is temperature in C):

The standard potential Bk/Bk is 2.01 V. The ionization potential of a neutral berkelium atom is 6.23 eV.

It is used as a redox indicator with standard potential +1.06 V. The reduced ferrous form has a deep red colour and the oxidised form is light-blue.

(The more exact standard potential given by an IUPAC review paper is 0.22249 V, with a standard deviation of 0.13 mV at 25 C.)

When an externally applied potential is greater than the standard potential for the discharge reaction, lithium metal is plated out on the anode, and O is generated at the cathode.

Water splitting can be done at higher pH values as well however the standard potentials will vary according to the Nernst equation and therefore shift by -59 mV for each pH unit increase.

When appropriately constructed, the silver chloride electrode can be used up to 300 C. The standard potential (i.e., the potential when the chloride activity is 1 mol/kg) of the silver chloride electrode is a function of temperature as follows:
