Oxidising potential

The oxidation of Hg to Hg2 + requires a smaller (less oxidising) potential than...

This large and commonly used class of salts covers a wide range of oxidising potential. Among the more powerful oxidants are those grouped for which separate entries emphasise the individual features. Some less highly oxidised anions function as reducants which also have a separate entry. Individually indexed entries are ... 

In common with enzyme based biosensors (equations (7.3) and (7.4)) the reduced mediator can be re-oxidized when it diffuses to an electrode poised at a suitably oxidising potential, e.g.,... 

There is a range of oxidants that are currently used as bleaching agents. They have a wide range of oxidising potential (Table 8). 

A continued reduction in the oxidising potential, moving further towards the lower left-hand side of the diagram, causes the A/ + ion to be replaced by more stable metal, M°. The boundary between the stability fields for M + and is horizontal, for the reason given above. 

The dependence of the cell voltage (which is a measure of the oxidising potential as well as the free energy of the reaction) as a function of the concentrations of the species present is expressed via the Nemst equation as ... 

Ozone is known to reduce plant yield and its toxicity is largely due to its oxidising potential. Upon dissolving in water, activated oxygen species such as hydrogen peroxide and the superoxide and hydroxyl radicals are formed (3). It is predominantly through these reactive intermediates that ozone toxicity is thought to be expressed. 

A typical shape for the current response of a CV of an electrochemically reversible redox couple is shown in Figure 2.4. This is plotted according to the lUPAC convention with positive (oxidising) potentials increasing from left to right.
