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. a. What are the concentration of carbonate in each of the saturated solutions of A2CO3and BCO3? b. What are the Ksp values of A2CO3 and BCO3? c. If 8.721 mg A2CO3 and 1.769 mg BCO3 were needed to prepare the saturated solutions, what are the identity of A2CO3and BCO3 ? Hint: deduct the molecular weight of carbonate d. Instead of distilled water, 250.0 mL of 0.10 M ANO3 was used to prepare a saturatedsolution of A2CO3 while 250.0 mL of 0.10 M B(NO3)2 was used for BCO3. Which will have a higher solubility?
