Question

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

• A. X
• B. Z
• C. both X and Z
• D. neither X nor Z

Answer 1

The correct option is A X

(X and Z)
Since $E_{red}^{\ominus }$ of Y > X, therefore Y will oxidize X.
Similarly, $E_{red}^{\ominus }$ of Y < Z, therefore Y will not oxidize Z.
