Given the standard electrode potentials
`K^(+)//K=-2.93V,Ag^(+)//Ag=0.80V`
`Hg^(2+)//Hg=0.79V`
`Mg^(2+)//Mg=-2.37V,Cr^(3+)//Cr=-0.74V`
Arrange these metals in their increasing order of reducing power.

Text Solution

Verified by Experts

More is `E_(RP)^(@)`, more in the tendency to get reduced or more is the oxidising power or lesser is reducing power.
`Ag lt Hg lt Cr lt Mg lt K`

The potential associated. with each electrode is known as electrode potential. If the concentration of each species taking part in the electrode reaction is unity (if any gås appears in the electrode reaction, it is confined to 1 atmospheric pressure) and further the reaction is carried out at 298 K, then the potential of each electrode is said to be the standard electrode potential. By convention, the standard electrode potential of hydrogen electrode is 0:0 volt. The electrode potential value for each electrode process is a measure, of relative tendency of the active species in the process to remain in the oxidized / reduced form. A negative E^@ means that the redox couple is a stronger reducing agent than the H^(+)//H_2 couple. A positive E mears that the redox couple is a weaker reducing agent than. the H^(+)//H couple. The metal with greater positive value of standard reduction potentlal forms the oxide of greater thermal stability: Given the standard reduction potentials.
