###### FREE Expert Solution

Figure out the Ksp equation of magnesium carbonate(MgCO3) and determine the Ksp using the provided concentration of 3.16x10-3 M or mol/L

The dissociation of MgCO3 in water are as follows:

MgCO3(s)  ⇌  Mg2+ (aq) + CO32- (aq)

We can construct an ICE table for the dissociation of MgCO3. Remember that solids are ignored in the ICE table.
