A 1 L solution contains 0.25 M Ni(NO3)2 and 0.25 M Cu(NO3)2. A. Can the metal ions be separated by slowly adding Na2CO3? Assume that for successful separation 99% of the metal ion must be precipitated before the other metal ion begins to precipitate, and assume no volume change on addition of Na2CO3. Justify your answer by showing step by step solution (with rationale), including equilibria equations.

Question
A 1 L solution contains 0.25 M Ni(NO3)2 and 0.25 M Cu(NO3)2.
A. Can the metal ions be separated by slowly adding Na2CO3? Assume that for successful separation 99% of the metal ion must be precipitated before the other metal ion begins to precipitate, and assume no volume change on addition of Na2CO3. Justify your answer by showing step by step solution (with rationale), including equilibria equations.
Ksp of CuCO3 = 1.4 x10-10
Ksp of NiCO3 = 1.42X 10-7
B. What would be the Molarity of Na2CO3 you will use in A , so that assumption of no volume change on addition of Na2CO3 will be valid ?
