SUMMARY
The maximum concentration of calcium ions [Ca2+] that can exist without precipitation in a solution containing 5.2e-4 M oxalate ions (C2O4 2-) can be calculated using the solubility product constant (Ksp) for calcium oxalate (CaC2O4), which is 2.6e-9. The relationship between Ksp and the concentrations of the ions in solution is critical for determining the maximum [Ca2+]. The formula for Ksp is Ksp = [Ca2+][C2O4 2-], which must be applied to find the maximum [Ca2+] that avoids precipitation.
