A solution contains 0.0500 M Co2+and 0.0500 M Ni2+. Is it possible to lower the concentration of Co2+by 99.9% without precipitating Ni2+by adding Na2CO3to the solution? Ksp,CoCO3= 1.0 x 10-10and Ksp,NiCO3= 1.3 x 10-7
Please show work so I can understand why this is the answer!
Answer: Yes, it is possible. (QNiCO3 < Ksp,NiCO3, no precipitation)
