Using E° values of -0.14 V for Sn²⁺/Sn and -0.13 V for Pb²⁺/Pb, what is the standard cell potential of a Sn-Pb cell?
Answer and explanation
Correct answer: C. 0.01 V
- Step 1: E° cell = E° cathode - E° anode.
- Step 2: = -0.13 - (-0.14) = 0.01 V.
Answer
0.01 V.
Why not the others: -0.27 V, -0.01 V and 0.11 V do not fit.
