The Ksp values of two solid carbonates, A2CO3 and BCO3, were determined by preparing 250.0-mL saturated aqueous solutions of both solids and then determining the concentration of carbonate by titrating it with 0.01023 M HCl up to methyl orange endpoint. Solutions of A2CO3 and BCO3 required 6.184 mL and 3.456 mL of the titrant, respectively.d.
