9. EMF for circuits at 298 K:
Be | Be acetonate dissolved in propylamine | Hg, Be
c = 0.01 M
And
Be, Hg | BeCl2(aq) || KCl(aq) | Hg2Cl2, Hg
c1 = 0.01 M c2 = 3.5 M
are 0.938 and 1.299 V. The potential of the calomel electrode is 0.250 V. Calculate the potential for the Be2 |Be electrode. The concentrations of amalgams are the same. Answer: -1.987 V.
