Question
Post lab Write the cell notation for the reaction: Cd^2+(aq) + Ni(s) rightarrow Cd(s) + Ni^2+(aq) Write the overall chemical reaction and calculate E degree for the following reduction and oxidation half-reactions. 2H^+(aq) + 2e^- rightarrow H_2(g) E degree_red = 0.000v Zn(s) rightarrow Zn^2+(aq) + 2e^- E degree_ax = 0.762v The standard oxidation potential, E degree_ax of Cu(s) is -0.339 v. The oxidation product is the copper(II) ion Write the equation for the standard potential. What is the value of the standard reduction potential, E degree_red?Explanation / Answer
1) Ni | Ni2+ || Cd2+ | Cd
2) Zn(s) + 2H+(aq) Zn2+(aq) + H2(g)
3) Cu (s) + 2e- --> Cu2+(aq) Eored = 0.339 V
