Anion Tests.

Particular ions present in solutions can be detected by precipitate reactions 

In order to test to see if a solution has sulphate ions in it you can use barium sulphate. If barium chloride solution is added to a sample of water containing sulphate ions , barium sulphate is formed which is insoluble in water and can be seen as a white precipitate

barium chloride solution + sodium sulphate solution ------> sodium chloride solution + solid barium sulphate
