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 ?
A
Electrode of half-cell potential –0.76 V serve as cathode
B
Electrode of half-cell potential –0.76 V serve as anode
C
Electrode of half-cell potential –0.13 V serve as anode
D
Electrode of half-cell potential – 0.76 V serve as positive electrode and –0.13 V as negative electrode
Answer
Electrode of half-cell potential –0.76 V serve as anode
Explanation
Solution
The electrode with more negative reduction potential
constitute the anode.
