Two half cells have reduction potentials –0.76 V and – 0.13 V respectively. A galvanic cell is made from these two half cells. Which of the following statements is correct?
  1. Electrode of half-cell potential –0.76 V acts as cathode
  2. Electrode of half-cell potential –0.76 V acts as anode
  3. Electrode of half-cell potential –0.13 V acts as anode
  4. Electrode of half-cell potential – 0.76 V acts as positive electrode and –0.13 V as negative electrode

Solution

According to the electrochemical series, the electrode with high reduction potential will act as a cathode, and the electrode with more negative reduction potential acts as the anode. *
