$A$ 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
- A$Y$ will oxidize $X$ and not $Z$
- B$Y$ will oxidize $Z$ and not $X$
- C$Y$ will oxidize both $X$ and $Z$
- D$Y$ will reduce both $X$ and $Z$

View SolutionThe standard electrode potentials at $25\,^oC$ for the following half-reactions are given:
$Zn^{2+} + 2e^- \to Zn, E^o = -0.762\,V$
$Mg^{2+} + 2e^- \to Mg, E^o = -2.37\,V$
When zinc dust is added to a solution of $MgCl_2$,what happens?
$Zn^{2+} + 2e^- \to Zn, E^o = -0.762\,V$
