What is the reduction electrode potential (in volts) of copper electrode when [ Cu ²⁺ ]=0.01 M is in a solution at 25^ C ? (E^ . of Cu ²⁺ / Cu electrode is .+0.34 ~V )
Options
- A0.3991
- B0.2809
- C0.3105
- D0.3695
Correct answer
B. 0.2809
Step-by-step solution
aligned E_ cell & =E_ cell ^ + 0.0591 n [M⁺ ] & =0.34+ 0.0591 2 [0.01] & =0.34- 0.0591 2 2 & =0.2809 volt aligned
