A gas $X$ at $1$ atm is bubbled through a solution containing a mixture of $1 \mathrm{~MY}^{-} ~\& ~1 \mathrm{~MZ}^{-}$ at $25^{\circ} \mathrm{C}$. If the reduction potential of $\mathrm{Z}>\mathrm{Y}>\mathrm{X}$, then
  1. $\mathrm{Y}$ will oxidize $\mathrm{X}$ and not $\mathrm{Z}$
  2. $\mathrm{Y}$ will oxidize $\mathrm{Z}$ and not $\mathrm{X}$
  3. $\mathrm{Y}$ will oxidize both $\mathrm{X}$ and $\mathrm{Z}$
  4. $\mathrm{Y}$ will reduce both $\mathrm{X}$ and $\mathrm{Z}$

Solution

The tendency to gain electron is in the order $\mathrm{Z}>\mathrm{Y}>\mathrm{X}$
Thus $Y+e^{-} ightarrow Y^{-} ; \quad X ightarrow X^{+}+e^{-}$. ^
