Question

A gas $X$ at $1$ atm is bubbled through a solution containing a mixture of $1M$ $Y^-$ and $1 MZ^-$ ions at $25 ^\circ C$. If the reduction potenital of $Z > Y > X$, 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)

$Y$ will oxidise $X$ but not $Z$

Answer 2

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