Electrochemistry 1 Question 16

16. The gas $X$ at $1 \mathrm{atm}$ is bubbled through a solution containing a mixture of $1 \mathrm{M}^{-}$and $1 \mathrm{MZ}^{-}$at $25^{\circ} \mathrm{C}$. If the order of reduction potential is $Z>Y>X$, then

$(1999,2 \mathrm{M})$

(a) $Y$ will oxidise $X$ and not $Z$

(b) $Y$ will oxidise $Z$ and not $X$

(c) $Y$ will oxidise both $X$ and $Z$

(d) $Y$ will reduce both $X$ and $Z$

Show Answer

Answer:

Correct Answer: 16. (a)

Solution:

  1. Higher the value of reduction potential, stronger the oxidising agent.

$ \because \quad E^{\circ}: Z>Y>X $

$\Rightarrow \quad Y$ will oxidise $X$ but not $Z$.
