Excess solid Na₂CO, is added to a solution containing 0.800 M (each) Mg²+ and Zn²+ ions. Ksp for MgCO₂ is 3.50 x 108 and Ksp for ZnCO, is 1.00 × 10¹1⁰. ZnCO., with the smaller Ksp, will be the least soluble and will begin precipitating first. What will be the [Zn²+] concentration when MgCO, just begins to precipitate? (Assume no volume change upon addition of the solid Na₂CO₂). 1 4 7 +/- 2 5 8 | M 3 6 9 0
