Q. Consider the following reduction processes :
$ Zn ^2+2 e ^{-} \longrightarrow Zn ( s ) ; E ^{\circ}=-0 \cdot 76\, V $
$Ca ^2+2 e ^{-} \longrightarrow Ca ( s ) ; E ^{\circ}=-2 \cdot 87\, V$
$Mg ^2++2 e ^{-} \longrightarrow Mg ( s ) ; E ^{\circ}=-2 \cdot 36\, V $
$ Ni ^2+2 e ^{-} \longrightarrow Ni ( s ) ; E ^{\circ}=-0 \cdot 25\, V$
The reducing power of the metals increases in the order:

Solution:

Higher the oxidation potential better will be reducing power.
