Question

The standard reduction potential values of three metallic cation `X, Y, Z` are `0.52, -3.03` and `-1.18 V` respectively. The order of reducing power to the corresponding metals is:
A. `Y gt Z gt X`
B. `X gt Y gt Z`
C. `Z gt Y gt X`
D. `Z gt X gt Y`,

Answer 1

Correct Answer - A
More is `E_(RP)^(@)`, more is the tendency to get reduced or more is the oxidizing power or lesser is reducing power. Thus
Oxidizing power `= X^(+) gt Z^(+) gt Y^(+)`
Reducing power `= Y gt Z gt X`
