Question
Calculate the cell potential for the following Galvanic cell:
Co(s) Co2+ (0.15 mol L-1, ag)Fe 2+ (0.68 mol L-1, ag)Fe(s)
Given that the standard reduction potential Eo for Co2+ is -0.28 V and Eo for Fe2+ is -0.44 V.
Anwer is -0.14 V
The left side of the above equaton is the annode and the right the cathode therefore -0.44 - -0.28 = -0.16 which is incorrect. What steps are taken showing maths and answer of -0.14. Are charges included?
maths to get -0.14 V.
