Question

81) Barium chloride on reacting with ammonium sulphate
forms barium sulphate and ammonium chloride. This
chemical reaction is an example of
A) Double displacement reaction
B) Decomposition reaction
C) Displacement reaction
D) Combination reaction​

Answer 1

This reaction is a double displacement reaction as well as a precipitation reaction. This is a double displacement reaction because one component of each compound has exchanged places with each other. It is also called a precipitation reaction due to the formation of white precipitate of barium sulphate. Rest other products formed are soluble in water except barium sulphate that precipitates out.
