Which of the following barium salts should dissolve in a strong acid such as HCl: Ba(OH)2, BaSO4, or BaCO3?
I thought they all would be that can't be the answer, can you explain how you know?
The cations Ba 2+ and Sr 2+ can be precipitated as very insoluble sulfates.
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?
I got this part right it is BaSO4 (Ksp = 1.1x 10-10). It is less soluble than SrSO4 (Ksp 3.4 x 10-7)
b) What will be the concentration for the first ion that precipitates when the second, more soluble salt begins to precipitate?
I don't know how you do these but the answer key says 1.8 x 10-7 M. Can you explain this to me?
