In my school's chemistry lab, I was asked to take some salt in a test tube and add barium chloride solution in it.A white precipitate was formed.I was told that this precipitate is insoluble in conc.HCL.But I didnot get any information regarding the name of the salt used and the precipitate formed.Can you name the salt and the precipitate.

Expert Answer:

That precipitate was BaSO4. The salt you took was a sulphate. This test is used to check if any sulphate is present in the salt or not. If you obtain a white ppt which is insoluble in HCl, this confirms that the salt has sulphate.
