Electrolysis is a phenomenon where a reaction is carried out by passing electricity through the molten electrolyte or the electrolytic solution in water. In electrolysis, electrolyte first decomposes into anions and cations and thereafter anions undergo oxidation at anode and cations undergo reduction at cathode. for example.
XY (molten ) `hArrX^(n+)+Y^(n-)`
Oxidation at anode : `Y^(n-)-"ne"^(-)rarrY`
Reduction at cathode `X^(n+)+ "ne"^(-)rarrX`
In order to predict the electrolytic products accurately an array of substances is arranged in decreasing order tendency of oxidation of the substances or increasing order of standard reducton potential in electrochemical series. the standard electrode potentials of some species (elements,or ions) is given as under.
`Cl_(2)(g)+2e^(-)rarr2Cl^(-),E^(@)=1.360V`
`Na^(+)+e^(-)rarrNa,E^(@)=-2.71V`
`2H_(2)O+e^(-)rarrH_(2)(g)+2OH^(-),E^(@)=-0.83V`
`2H^(+)+2e^(-) rarrH_(2),E^(@)=OV`
