The standard electrode potential of in aqueous solution does not depend on
Multiple Choice Options
- A Ionisation of a gaseous metal atom
- B Sublimation of a solid metal
- C Ionisation of a solid metal atom
- D Hydration of a gaseous metal ion
Step-by-Step Verified Solution
The standard electrode potential (E°) of a metal ion M+/M in aqueous solution is calculated under standard conditions and relates to the tendency of the M+ ion to gain an electron to form the neutral metal atom, M.
This is indeed a redox (reduction-oxidation) process, and the standard electrode potential is defined for the reduction half-reaction. E° values are based on the energies involved in the processes of ionization and hydration.
However, the standard electrode potential does not depend on the state (solid, liquid, gas) of the atom being ionized. Ionization of a solid metal atom (Option C) would not directly impact the electrode potential as it is not inherently part of the process of reduction at the electrode that the E° values are measuring.
The correct answer should be Option C : Ionisation of a solid metal atom.
