What is the Ecell value for the following Sn2 2e Sn E0 014

What is the Ecell value for the following:

Sn²⁺ + 2e^- -> Sn, E⁰= -0.14V

Cu²⁺ + 2e^- -> Cu, E⁰= 0.34V

A) 0.20V

B) -0.48V

C) 0.48V

D) -0.20V

E) -0.34V

Solution

The difference between the anode\'s potential to become reduced and the cathode\'s potential to become reduced is the cell potential.

Note:

E_cell =E_right-Eleft

=0.34+0.14

=0.174 V
