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.

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.
