Question

If an element has more negative value of electrode potential, then what will be its expected reducing power?

Answer 1

In general conditions of M^​n+/M species, more the value of negative electrode potentioal more will be its reducing power.
Actually, electrode potential goves the tendency to acquire electrons and if this value is negative the element will have tendency to lose electrons and so they become oxidezed and reduces the other species which shows their increased reducing power.
