Given the standard electrode potentials,

^{+}

/K = –2.93 V, Ag

^{+}

/Ag = 0.80 V, Hg

^{2+}

/Hg = 0.79 V, Mg

^{2+}

/Mg = –2.37 V, Cr

^{3+}

/Cr = – 0.74 V

Arrange these metals in their increasing order of reducing power.

Solution:

Higher the oxidation potential, more easily it is oxidized and hence greater is the reducing power. Thus, increasing order of reducing power will be

Ag < Hg < Cr < Mg < K.
