Electrochemical series : The arrangement of electrodes (metal or non-metal in contact with their ions) with the electrode half reaction in order of decreasing standard potential is known as electrochemical series.
Applications of electrochemical series :
(i) Relative strength of oxidising agents in terms of `E^(@)` values can be calculated.
(ii) Relative strength of reducting agents in terms of `E^(@)` values can be calculated.
(iii) To identify the spontaneous direction of reaction.
(iv) To calculate the `E_("cell")^(@)` values.
`E_("cell")^(@)=E_("RHE")^(@)-E_("LHE")^(@)`
