1.Which of the following barium salts should dissolve in a strong acid such as HCl: Ba(OH)2, BaSO4, or BaCO3? Can you explain why please?
2.The cations Ba 2+ and Sr 2+ can be precipitated as very insoluble sulfates.BaSO4 (Ksp = 1.1x 10-10) SrSO4 (Ksp 3.4 x 10-7)
a) If you add sodium sulfate to a solution containing these metal cations, each with a concentration of 0.10 M, which is precipitated first, BaSO4, or SrSO4?
b) What will be the concentration for the first ion that precipitates when the second, more soluble salt begins to precipitate?
