Use the equation Eºcell=Eº cathode - Eº anode where Eºcell is the standard cell potential, Eºcathode is the standard potential for the reduction half-reaction, and Eºanode is the standard potential for the oxidation half-reaction.

Question

Calculate the standard electrode potential of the copper electrode if the standard electrode potential of the zinc electrode is -0.76 V and the standard cell potential is 1.10 V for the cell reaction: Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s). Use the equation Eºcell=Eº cathode - Eº anode where Eºcell is the standard cell potential, Eºcath

Answer 1

To calculate the standard electrode potential of the copper electrode, we can use the equation Ecell = Ecathode - Eanode. We are given the standard electrode potential of the zinc electrode  Eanode  as -0.76 V and the standard cell potential  Ecell  as 1.10 V.We can rearrange the equation to solve for Ecathode  the standard electrode potential of the copper electrode :Ecathode = Ecell + EanodeNow, we can plug in the given values:Ecathode = 1.10 V +  -0.76 V Ecathode = 0.34 VSo, the standard electrode potential of the copper electrode is 0.34 V.
