Question

A gas X at 1 atm is bubbled through a solution containing a mixture of 1 M Y^- and 1 M Z^+ at 25C. If 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

Hint:

Species with higher reduction potential acts as oxidising agent.

Answer 1

The Correct Option is A

Step 1: Reduction potential order. Higher reduction potential oxidises lower ones.
Step 2: Reaction feasibility. Y oxidises X but cannot oxidise Z.
