Question

Can you pls check all the answers of Thanks An electrochemical cell, composed of an iron electrode (anode) immersed in 0.10 M Fe(NO3)2 a cell potential of 1.21 V. The standard reduction potential for the Ag'IAg halt +0.80 V. The standard reduction and a silver electrode (cathode) immersed in 0.11MAgNOs, was found to have on potential for the Ag' Ag half-cell is potential for the Fe /Fe half-cell is 0.45 V. a. Write the half-cell reaction at the anode. b. Write the half-cell reaction at the cathode. c. Write the overall cell reaction. d. Determine the standard cell potential () using the standard reduction potentials given above 0.80-(-0.48 = . Determine the standard cell potential (e a) using the Nenst eqyation. 0.05 = 1.25-0.0271 oil)

Explanation / Answer

a) Reaction at anode

Fe(s) ------- Fe(+2)(aq) + 2e-, Eo(oxidation) = 0.45V

b) Reaction at cathode

2Ag+(aq) + 2e- ---------- 2Ag(s), Eo(reduction) = 0.80V

c) Overall cell reaction

Fe(s) + 2Ag+(aq) ---------- Fe(+2)(aq) + 2Ag(s)

d) Eocell = Eo(oxidation) + Eo(reduction)

=> 0.45 + 0.80

=> 1.25

e) Using the nernst equation

Ecell = Eocell - 0.0591/2 * log(0.10/(0.11)^2)

=> 1.25 - 0.02710

=> 1.2222
