What causes a precipitate to form when barium hydroxide solution and sulphuric acid are mixed?

When barium hydroxide solution is mixed with sulfuric acid, a white precipitate of barium sulfate is formed due to a double displacement reaction. Barium sulfate is insoluble in water and thus forms a solid precipitate. This reaction is used in chemistry labs to test for the presence of sulfate ions.

Why does silver nitrate test provide negative result on the presence of a chloride ion?

The silver nitrate test provides a negative result on the presence of a chloride ion because silver chloride is insoluble in water and forms a white precipitate when silver ions react with chloride ions. This precipitate masks the presence of the chloride ion in the test solution, giving a negative result.
