Precipitation of "calcium carbonate"

Explanation:

Ca(NO_3)_2(aq) + Na_2CO_3(aq) rarr 2NaNO_3(aq) + CaCO_3(s)

Or, since the nitrate and sodium ions are along for the ride, we could write a net ionic equation:

Ca^(2+) + CO_3^(2-) rarr CaCO_3(s)darr

Calcium carbonate is very poorly soluble in water; I think, from memory, to the tune of 15*mg*L^-1.

In acidified water, would you expect calcium carbonate to have greater solubility?
