Question

If the half cell reaction $A+e^{-}\to A^{-}$ has a large negative reduction potential, it follows that:

• A. A is readily reduced
• B. A is readily oxidised
• C. A${}^{-}$ is readily reduced
• D. A${}^{-}$ is readily oxidised

Answer 1

The correct option is D A${}^{-}$ is readily oxidised

As we know,

$E_{OP}^o=-E_{RP}^o=+ve$. Large positive value means it has high tendency to oxidise. So $A^{-}$ is readily oxidised.
