Calcium oxalate is a sparingly soluble ionic compound composed of calcium ions (Ca2+) and oxalate ions (C2O42–). It is a main culprit in kidney stone disease due to the formation of calcium oxalate crystals in the urine. A typical value for the concentration of calcium in urine is 0.3 grams per liter. Given a Ksp value for calcium oxalate of 1.3 × 10–8, calculate the minimum concentration of oxalate ion in urine that could lead to precipitation of calcium oxalate.
