Homework Statement
Is it possible to precipitate 99.0% of 0.010 M Ce3+ by adding oxalate (C2O42-) without precipitating 0.010 M Ca2+
CaC2O4 Ksp = 1.3 x 10-8 Ce2(C2O4)3 Ksp = 5.9 x 10-30
Homework Equations
1.3x10-8 = [0.01M][C2O4-]
5.9x10-30=[0.01M]2[C2O4]3
The Attempt at a Solution
All I've been able to do is set up those Ksp equations but I'm not sure what to do from here
