It is of interest to decide if an analytical separation of the metal ions can be effected by selective precipitation of carbonates from a solution that is 9.71x10-2 M in Mn2+ and 0.100 M in Ni²+ Ksp = 6.60x10-9 Kp = 1.80x10-11 NICO Use the References to access important values if needed for this question. MnCO3 To analyze this problem, answer the following questions. (1) What carbonate concentration is needed to precipitate 99.9% of the metal that forms the least soluble carbonate? (2) When 99.9% of the least soluble carbonate has precipitated, will all of the metal that forms the more soluble carbonate still remain in solution? (3) What is the upper limit on the carbonate ion concentration if the more soluble compound is not to precipitate? (4) If the [CO32] is at this upper limit, what percentage of the metal that forms the least soluble carbonate remains in solution? M M
