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.

How do you disprove the presence of sodium sulphate in a compound. Any tests or procedures or methods?

The sulfate ion is precipitated with barium chloride.The presence of sodium can be tested by flame photometry.


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.
