Given the standard electrode potentials
`K^+//K= -2.93V, Ag^+//Ag = +0.8V, Hg^(2+)//Hg= 0.79 V, Mg^(2+)//Mg = -2.36V Cr^(3+)//Cr = 0.74 V`
Arrange them in increasing order of reducing power.

Text Solution

Verified by Experts

Lower the electrode potential, better is the reducing power. Hence the reducing power decreases in the order `KgtMg gtCrgtHg gtAg`
