उत्तर
A white precipitate can be obtained by adding dilute sulphuric acid to BaCl2 solution.
Explanation:
When dilute sulphuric acid (H2SO4) reacts with barium chloride (BaCl2), a double-displacement reaction occurs, forming an insoluble white precipitate of barium sulphate (BaSO4). The balanced equation is:
\[\ce{BaCl2_{(aq)} + H2SO4_{(aq)} -> BaSO4_{(s)}\downarrow + 2HCl_{(aq)}}\]
