Question

The standard reduction potential values of three metallic cations, x, y, z, are 0.52, - 1.18V respectively. The order of reducing power of the corresponding metal is :

Options

A.y > z > x
B.x > y > x
C.z > y > x
D.z > x > y

Solution

Higher is the EoR.P.higher is the tendency to get reduced, higher is the oxidising power or weaker is the reducing agent, thus
Oxidising power = x+ > z+ > y+
Rducing power = x > z > y
