1) For the precipitation reaction of calcium oxalate below, the Ks = 3.7x10 Note: For this question, do not apply the small x approximation. A) If excess calcium oxalate were added to 100.0 mL of pure water, what concentration of calcium ions and oxalate ions would be expected when the solution is saturated? B) If 1.00 mg of calcium chloride were then added to the mixture (assume no solution volume change and complete dissolution and dissociation of CaCl2), what would be the expected concentrations of calcium ions and oxalate ions once equilibrium is reestablished? Ca2+(aq) + C2042(aq) ⇄ CaC204(s)
