Calculate the molar solubility of CaCO3.
Here we have to calculate the molar solubility of CaCO3.
Ksp of CaCO3 is 4.8x10-9
CaCO3 dissociate to give ,
CaCO3 (s) Ca2+ (aq) + CO32- (aq)
let x = mol/L CaCO3 that dissolve : we get x mol/L Ca2+ and x mol/L CO32- ion.
Ksp = [Ca2+][CO32-]
4.8x10-9 = (x)(x)
