Calculate the molar solubility of caco3 in water


From the hard water the slaked lime, Ca (OH)2 is used to soften hard water by removing the calcium ions through the following reaction.

Ca (OH)2(aq) +Ca2+(aq) + 2HCO3-(aq) → 2CaCO3(s) + 2 H2O(l)

Although CaCO3 is considered insoluble, some of it does dissolve in the aqueous solutions. Calculate the molar solubility of CaCO3 in water (where Ksp =8.7 x 10-9).
