Question

Standard cell potential is calculated as:

  1. A
    Ecell∘=Ecathode∘−Eanode∘E^\circ_{cell}=E^\circ_{cathode}-E^\circ_{anode}
    Correct
  2. B
    sum of both electrode potentials
  3. C
    Eanode∘−Ecathode∘E^\circ_{anode}-E^\circ_{cathode}
  4. D
    always 1.10 V

Correct answer

Ecell∘=Ecathode∘−Eanode∘E^\circ_{cell}=E^\circ_{cathode}-E^\circ_{anode}

Explanation

Reduction potentials are combined as cathode minus anode.
