(a) Calculate the standard potential for the reaction Cu(s) + Br2 CuBr(s)

(a) Calculate the standard potential for the reaction Cu(s) + Br2 CuBr(s) + e For CuBr, Ksp = 5.2 X 10-9. (b) Give a schematic representation of a cell with a copper indicator electrode and a reference SCE that could be used for the determination of Br2. (C) Derive an equation that relates the measured potential of the cell in (b) to pBr (assume that the junction potential is zero). (d) Calculate the pBr of a bromide-containing solution that is saturated with CuBr and contained in the cell described in (b) if the resulting potential is - 0.095 V.
