उत्तर
Sulphuric acid precipitates the insoluble sulphate of barium from the solution of barium chloride.
\[\ce{BaCl2 + H2SO4 -> BaSO4\downarrow + HCl}\]
\[\ce{BaCl2 + HCl -> No ppt. formation}\]
Dilute HCl does not react with barium chloride solution, and thus, no precipitate is produced in the reaction.
