Question

A gas $z$ is bubbled through a solution containing $x ^{-}$ and $y ^{-}$. If the reduction potential are in the order $x>y>z$, then

• A. y will oxidise z and not x
• B. y will oxidise x and not z
• C. y will oxidise both x and z
• D. y will reduce both x and z

Answer 1

Answer: (A)

y will oxidise z and not x

Answer 2

More is the value of reduction potential, more is the tendency to get reduced. So as z gas has lowest reduction potential, therefore, z will be oxidised easily
