Question

Which of the following is/are true regarding oxidation potential?

• A. It is electrode potential for oxidation half cell
• B. It is electrode potential for reduction half cell
• C. It corresponds to positive electrode
  
• D. It corresponds to negative electrode

Answer 1

Answer: (A), (D)

It corresponds to negative electrode

Electrode potential for oxidation half cell reaction is called oxidation potential. The corresponding electrode is termed as negative electrode.
For a given oxidation half cell reaction,
$M\left(s\right)\to M^{n+}\left(aq\right)+n{e}^{-}$

The shorthand notation for oxidation potential is
$E_{M\left(s\right)/M^{n+}\left(aq\right)}^{\circ }$
