Question- A solution contains a mixture of 0.25 M Ni2+ and 0.25 M Cu2+. Na2CO3 is slowly added to the solution in order to separate the ions by selective precipitation. What is the [Cu2+] when NiCO3 begins to precipitate? Is this an effective way to separate the ions? Explain. Ksp for CuCO3 = 3.0 *10-12; Ksp for NiCO3 = 5.2*10^-7.
Please perform what you can and illustrate your work so I can follow. Thanks
