What is the standard potential of cell Ni | Ni ²⁺ _ (1 M ) | Cu ²⁺ _ (1 M ) | Cu If E ^ Cu =0 337 ~V and E ^ Ni =-0 236 ~V
Options
- A0 101 ~V
- B-0 136 ~V
- C0.573 ~V
- D-0.753 ~V
Correct answer
C. 0.573 ~V
Step-by-step solution
aligned E _ ceil ⁰ &= E _ cuthode ⁰- E _ anode ⁰= E _ Cu ⁰- E _ Ni _ i ⁰ &=0.337 ~V -(-0.236 ~V )=0.573 ~V aligned
