The half-cell reactions with their appropriate standard reduction potentials are
(i) Pb2+ + 2e– → Pb (E° = –0.13 V)
(ii) Ag+ + e– → Ag (E° = +0.80 V)
Based on the above data, which of the following reactions will take place?
(i) Pb2+ + 2e– → Pb (E° = –0.13 V)
(ii) Ag+ + e– → Ag (E° = +0.80 V)
Based on the above data, which of the following reactions will take place?
- Pb2+ + 2Ag → 2Ag+ + Pb
- 2Ag + Pb → 2Ag+ + Pb2+
- 2Ag+ + Pb → Pb2+ + 2Ag
- Pb2+ + 2Ag+ → Pb + Ag
Answer
(C) 2Ag + + Pb → Pb 2+ + 2Ag
