A solution of NaSCN is added dropwise to a solution that is 3.08e-02 M in Hg22+ and 1.74e-03 M in Cu+. The Ksp of Hg2(SCN)2 is 3.2e-20. The Ksp of CuSCN is 1.77e-13. Calculate the concentration of SCN- present in the Hg22+/Cu+ solution when the first (initial) cation begins to precipitate, and the concentration of SCN- present in this solution when the second (final) cation begins to precipitate. Write down which cation precipitates first and which precipitates second (last)
