Question

Barium chloride on reacting with ammonium sulphate forms barium sulphate and ammonium chloride, is a type of

• A. Decomposition reaction
• B. Double displacement reaction
• C. Combination reaction
• D. Redox reaction

Answer 1

The correct option is B Double displacement reaction

When barium chloride reacts with ammonium sulphate, it forms white precipitate of barium sulphate along with ammonium chloride. There is also an exchange of ions which results in the formation of product molecules. As a result, it is a precipitation as well as double displacement reaction. The reaction involved is:

${\text{BaCl}}_2$ + ${\text{(NH}}_4{)}_2{\text{SO}}_4\to {\text{BaSO}}_4\downarrow +2{\text{NH}}_4\text{Cl}$
