Q. The standard electrode potential ($E^\circ$) values of $Al^{3+}/Al$, $Ag^+/Ag$, $K^+/K$ and $Cr^{3+}/Cr$ are $-1.66\, V$, $0.80\,V$, $-2.93\, V$ and $-0.74\, V$, respectively. The correct decreasing order of reducing power of the metal is :

NEETNEET 2019Electrochemistry

Solution:

Reducing power of metal $\propto \frac{1}{SRP}$
$K > Al > Cr > Ag$.
