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. (10)
Solution:
- 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 $Z$.
