A beaker containing mixture of 1   M   Y and 1   M   Z . A gas X at 1 a t m is bubbled through this solution at 2 5 o C . If the reduction potential of Z > Y > X , then
Options
- AY will oxidize X and not Z
- BY will oxidize Z and not X
- CY will oxidize both X and Z
- DY will reduce both X and Z
Correct answer
A. Y will oxidize X and not Z
Step-by-step solution
From the reduction potential, the tendency to gain electron is in the order Z > Y > X Thus Y + e → Y - ; X → X + + e .
