8.29 Given the standard electrode potentials

K^{+}/K = -2.93 V   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.

Answer-

A negative electrode potential (E^{0})means redox couple is a stronger reducing agent. So as per data the increasing order of the following is-

Ag<Hg<Cr<Mg<K
