I did batch reactions where I dissolved NaCl in to 4N HCl solution and mass balanced it. I am getting about 116.5g/L @ a temperature of 22C. Is there a table available that i shows me the theoretical values at different temperatures? Any help is welcomed. Thank you for taking your time. I need this to finish my project.Answer Question

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?
