The standard reduction potential values of three metallic cations,X,Y,Z are 0.52,-3.03 and -1.18V,respectively.The order of reducing power of the corresponding metals is

$\begin{array}{1 1}Y > Z > X\\X > Y > Z\\Z > Y > X\\Z > X > Y\end{array} $

1 Answer

Answer : Y > Z > X
More negative the standard potential,least the tendency of the cation to be reduced.The corresponding atom has larger tendency for oxidation and hence larger reducing power.
