The E _ cell ^ of Cu _ ( s ) | Cu _ ( IM ) ⁺⁺ | | Ag _ ( IM ) ⁺ | Ag _ ( s ) is 0.647 volt. Calculate the E _ Ag ^ if E _ Cu _ u ^ is 0.153 V .
Options
- A0.8 V
- B0.5 V
- C-0.8 V
- D-0.5 V
Correct answer
A. 0.8 V
Step-by-step solution
The given cell is composed of copper electrode as the anode and silver electrode as the cathode. The standard cell potential is given by aligned & E _ cell ^ o = E _ cathode ^ o - E _ anode ^0 & E _ cell ^ o = E _ Ag ⁺ Ag ^0 ^0- E _ Cu ²⁺ Cu ^ o & E _ Ag ⁺ Ag ^ o = E _ cell ^0+ E _ Ou ^2+ Clu ^ ^ o & =(0.647 ~V )+(0.153 ~V )=0.8 ~V aligned
