Consider the reaction,

{M^{n + }}\left( {aq} \right) + ne \to {M^ \circ }\left( s \right).

The standard reduction potential values of the metals

{M_1},{M_2}

and

{M_3}

are

- 0.34\mathrm{V}, - 3.05\mathrm{V}

and

- 1.66\mathrm{V}

respectively. The order of their reducing power will be :

View answer and explanation

Correct option: D

{M_2} > {M_3} > {M_1}

Option D is correct because the reducing power of a metal is inversely related to its standard reduction potential. The metal with the most negative standard reduction potential is the strongest reducing agent. Therefore, the order of reducing power is M2 > M3 > M1.
