Vedclass · Answer

(A) The reduction potential represents the tendency to gain electrons. Given the order $Z > Y > X$,$Z$ has the highest tendency to be reduced,followed by $Y$,and then $X$.An oxidizing agent is a substance that gets reduced itself and oxidizes others. $A$ species with a higher reduction potential can oxidize a species with a lower reduction potential.Since the reduction potential of $Y > X$,$Y$ can oxidize $X$.Since the reduction potential of $Z > Y$,$Y$ cannot oxidize $Z$ (in fact,$Z$ would oxidize $Y$).Therefore,$Y$ will oxidize $X$ but not $Z$.

$A$ gas $X$ at $1 \, atm$ is bubbled through a solution containing a mixture of $1 \, M \, Y^{-}$ and $1 \, M \, Z^{-}$ at $25 \, ^oC$. If the reduction potential of $Z > Y > X$,then

For the feasibility of a redox reaction in a cell,the e.m.f. should be

The standard electrode potentials are: $K^{+}/K = -2.93 \ V$,$Ag^{+}/Ag = 0.80 \ V$,$Hg^{2+}/Hg = 0.79 \ V$,$Mg^{2+}/Mg = -2.37 \ V$,$Cr^{3+}/Cr = -0.74 \ V$. Arrange these metals in the increasing order of their reducing power.

The reaction $Zn^{2+} + 2e^{-} \to Zn$ has a standard electrode potential of $-0.76 \ V$. This means:
