For the following cell, standard potential of copper electrode in 0.337 ~V and standard cell potential is 0.463 ~V Cu | Cu ²⁺(1 M ) | Ag ⁺(1 M ) | Ag What is the standard potential of silver electrode?
Options
- A-0.126 ~V
- B0.800 ~V
- C-0.463 ~V
- D0.126 ~V
Correct answer
B. 0.800 ~V
Step-by-step solution
E _ cell ⁰=0.463 ~V , E _ Cu ⁰=0.337 ~V E _ cell ⁰= E _ Ag ⁰- E _ Cu ⁰ E _ Ag ⁰= E _ cell ⁰+ E _ Cu ⁰=0.463+0.337=0.800 ~V
