A gas X at 1 atm is bubbled through a solution containing a mixture of 1M Y and 1MZ ions at `25^(@)C` if the reduction potential of `ZgtYgtX`, then

Options

A. Y will oxidise X but not Z
B. Y will oxidise both X and Z
C. Y will oxidise Z but not X
D. Y will reduce both X and Z.

Answer

A

Explanation

Reduction potentials in the order `ZgtYgtX` means that Z can be reduced most easily and X least easily i.e., their oxidising powers are
`ZgtYgtX `
Hence Y will oxidise X but not Z.
