We’re being asked to determine Ksp of magnesium carbonate at 25 °C.
Recall that Ksp is an equilibrium constant related to slightly soluble ionic compounds.
The dissociation of magnesium carbonate in solution is as follows:
MgCO3(s) ⇌ Mg2+(aq) + CO32–(aq)
We can construct an ICE table for this dissociation.
Remember that solids are ignored in the ICE table and Ksp expression.
At 25 °C the solubility of magnesium carbonate is 3.16 x 10-3 mol/L. Calculate the value of Ksp at this temperature. Give your answer in scientific notation to 2 SIGNIFICANT FIGURES (even though this is strictly incorrect).
