Question

Solid BaF2 is added to a solution containing 0.2 mol of Na2C2O4 solution (2 L) until equilibrium is reached. If Ksp of BaF2 and BaC2O4 is 10^-8 (mol/L)^3 and 10^-9 (mol/L)^2 respectively. Find the concentration of [Ba^2+] in the solution. Assume addition of BaF2 does not cause any change in volume.
