Question: Answered & Verified by Expert
A gas $X$ at 1 atm is bubbled through a solution containing a mixture of $1 \mathrm{M} \mathrm{Y}^{-}$ and $1 \mathrm{M} \mathrm{Z}^{-}$ at $25^{\circ} \mathrm{C}$. If the reduction potential is $Z>Y>X$, then

Options:
  • A $\mathrm{Y}$ will oxidise $\mathrm{X}$ and $\mathrm{not} \mathrm{Z}$
  • B $\mathrm{Y}$ will oxidise $Z$ and $\mathrm{not} \mathrm{X}$
  • C $\mathrm{Y}$ will oxidise both $\mathrm{X}$ and $\mathrm{Z}$
  • D $\mathrm{Y}$ will reduce both $\mathrm{X}$ and $\mathrm{Z}$

The correct answer is: $\mathrm{Y}$ will oxidise $\mathrm{X}$ and $\mathrm{not} \mathrm{Z}$
The more the reduction potential, the more the oxidising power.
