Question

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

• A. $Y$ will oxidise $X$ but not $Z$
• B. $Y$ will oxidise both $X$ and $Z$
• C. $Y$ will oxidise $Z$ but not $X$
• D. $Y$ will reduce both $X$ and $Z$

Answer 1

Answer: (A)

Higher the value of reduction potential, stronger the oxidising agent.
$\because E^\circ:Z > Y> X$
$\Rightarrow $ $Y$ will oxidise $X$ but not $Z$.
