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?
Options
- AElectrode of half-cell potential – 0.76 V acts as cathode
- BElectrode of half-cell potential – 0.76 V acts as anode
- CElectrode of half-cell potential – 0.13 V acts as anode
- DElectrode of half-cell potential – 0.76 V acts as positive electrode and – 0.13 V as negative electrode
Correct answer
B. Electrode of half-cell potential – 0.76 V acts as anode
Step-by-step 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.
