Question

The standard reduction potential values of some of the p-block ions are given below. Predict the one with the strongest oxidising capacity.

Select the correct option:

${\rm{E}}_{{\rm{A}}{{\rm{l}}^{3 + }}/{\rm{Al}}}^ \ominus = - 1.66\;{\rm{V}}$

${\rm{E}}_{{\rm{T}}{{\rm{I}}^{3 + }}/T1}^ \ominus = + 1.26\;{\rm{V}}$

${\rm{E}}_{{\rm{S}}{{\rm{n}}^{4 + }}/{\rm{S}}{{\rm{n}}^{2 + }}}^ \ominus = + 1.15\;{\rm{V}}$

${\rm{E}}_{{\rm{P}}{{\rm{b}}^{4 + }}/{\rm{P}}{{\rm{b}}^{2 + }}}^ \ominus = + 1.67\;{\rm{V}}$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

Standard reduction potential value (+ve) increases oxidising capacity increases.
