Question

Given standard electrode potentials
`K^(o+)|K=-2.93V, Ag^(o+)|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.

Answer 1

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`
