Using E° values of -0.25 V for Ni²⁺/Ni and 0.34 V for Cu²⁺/Cu, what is the standard cell potential of a Ni-Cu cell?
Answer and explanation
Correct answer: C. 0.59 V
- Step 1: E° cell = E° cathode - E° anode.
- Step 2: = 0.34 - (-0.25) = 0.59 V.
Answer
0.59 V.
Why not the others: 0.09 V, -0.59 V and 0.69 V do not fit.
