Some wastewater stream contains 0.015 M Hg22+. Some chemical engineer decides to remove it by precipitating it as Hg2CO3(s). He mixes 100.00 ml of the wasterwater with 100.00 ml of a 2.00 M solution of Na2CO3 and filters the result to remove the solid. How much residual Hg22+ should he expect to find still in the water? (Hint: it should not be 0) Ksp of. Hg2CO3 = 9.0 x 10-15. Also keep in mind that Hg+ is the only ion that exists in solutions as a dimer, i.e. Hg22+, not 2 Hg+ (Hg2CO3→ Hg22+ + CO32-)
