Question

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

• A. Y will oxidize X and not Z
• B. Y will oxidize Z and not X
• C. Y will oxidize both X and Z
• D. Y will reduce both X and Z

Answer 1

The correct option is B Y will oxidize Z and not X

Order for Reduction potential

$Z>Y>X$

Higher reduction potential means self reduction of species but oxidises others (means oxidising agent)

Lower reduction potential means self oxidation of species but reduces others (means reducing agent)

Thus,

$Y$ will oxidise $X$and not $Z$.
