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
Given values are of `E_(RP)^(@) ` . Thus , `E_(RP)^(@)` order is `Y gt Z gt X` , more is `E_(OP)^(@)` , more is the tendency to get oxidise and thus more is the reduction nature .
