Question #53010

Answer 1

The given reactions are

`X^-2 + Y -> X +Y^-2........................(1)`

and

`X+Z^-2 -> X^-2 +Z..........................(2)`

Eq(1) reveals that Y is stronger oxidizing agent than X, because Y takes up 2electrons from `X^-2` forming `Y^-2`

Eq(2) reveals that X is stronger oxidizing agent than Z ,because X takes up 2electrons from `Z^-2` forming `X^-2`

So order of their of their oxidizing capacity is `Y>X>Z`

This implies that Y can oxidize both X and Z but X oxidizes Z

If we add this two equations (1) and (2) we get

`Z^-2+Y->Y^-2+Z...............................(3)`

Eq(3) reveals that Y is stronger oxidant than Z

Hence weakest oxidizing agent is Z
