NEET 2023 Phase 2 · ChemistryGalvanic & EMFPrevious Year Question

The correct option for a redox couple is

Answer: (A) Both the reduced and oxidized forms involve the same element. \textbf{Answer:} (A) Both the reduced and oxidized forms involve the same element.

  1. A.Both the reduced and oxidized forms involve the same element
  2. B.Cathode and anode together
  3. C.Both are oxidised forms involving the same element
  4. D.Both are reduced forms involving the same element

Correct Answer

(A) Both the reduced and oxidized forms involve the same element

Solution & Explanation

\textbf{Answer:} (A) Both the reduced and oxidized forms involve the same element. \textbf{Solution:} A redox (electrode) couple consists of the oxidised and reduced forms of the same species, written as oxidised/reduced, e.g. , or . Together these two forms of the same element define the electrode and its electrode potential. Hence option (A) is correct.
