उत्तर
White precipitate of barium sulphate is formed.
Explanation:
When a solution of zinc sulphate is added to a solution of barium chloride, a double displacement reaction occurs. This reaction involves the exchange of ions between the two compounds and a white precipitate of barium sulphate is formed.
\[\ce{ZnSO4_{(aq)} + BaCl2_{(aq)} -> BaSO4_{(s)} + ZnCl2_{(aq)}}\]
