Addition of an aqueous solution of `ZnSO_4` to an aqueous solution of `BaCl_2` is an example of __ reaction

Explanation

Addition of an aqueous solution of `ZnSO_(4)` to an aqueous solution of `BaCl_(2)` is an example of double displacement reaction. The reactions in which the ions in the reactants are exchanged to form a precipitate are called double displacement reactions. When an aqueous solution of `ZnSO_(4)` is added to an and aqueous solution of `BaCl_(2)`, `ZnCl_(2)` and white precipitate of `BaSO_(4)` are formed.
`{:(ZnSO_(4(sq))+BaCl_(2(aq))rarrBaSO_4darrZnCl_(2(aq))),(" Zinc " " Barium " " Barium " " Zinc"),(" sulphate " " chloride " " sulphate " " chloride"):}`
In this reaction `BaSO_4` is formed by an exchange of barium and sulphate ions present in the reactants. Hence, this reaction is an example of double displacement reaction.
