If I were to add aluminium sulfate solution to barium chloride solution, what would the precipitate be?
Answer:
The reaction is
2Al2(SO4)3 (aq) +6 BaCl2(aq) >>6 BaSO4 (s) +4 AlCl3 (aq)
The net ionic equation is
Ba2+ (aq) + SO42- ( aq) >> BaSO4 (s)
BaSO4 is a slightly soluble salt ; Ksp = 1.5 x 10^-9

A white precipitate of barium sulphate.
you would get aluminium chloride, which is soluable in water (so won't be a precipate)

and barium sulfate, which is a white crystalline solid with the chemical formula BaSO4. It is very insoluble in water and other traditional solvents, but is soluble in concentrated sulfuric acid. The mineral barite is composed largely of barium sulfate and is a common ore of barium.
BaSO4
A white precipitate of barium sulfate. I will never understand why people say sulphate?
