Question

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

• 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

Answer 1

The correct option is A Y will oxidise X and not Z

Higher the value of reduction potential, stronger the oxidising agent.
$\therefore$
$E^o:Z>Y>X$
$\Rightarrow \text{Y will oxidise X and not Z}$.
