Question

Standard electrode potential of three metals X, Y, and Z are -1.2 V, + 0.5 V and -3.0 V respectively. The reducing power of these metals will be

Options

A. Y > X > Z
B.Z > X > Y
C.X > Y > Z
D.Y > Z > X

Solution

EXo = - 1.2 V; EYo = + 0.5 V; EZo = - 3.0 V;
∴ Z > X > Y [higher the reduction potential, lesses the reducing power.]
