Answer 1

Answer:

Barium chloride (BaCl 2 ) reacts with sodium sulphite (Na 2 SO 3 ) to form barium sulphite (BaSO 3 ) and sodium chloride (NaCl).

BaCl 2(aq)+Na2 SO3 (aq)→BaSO3(s)+2NaCl(aq)

(white ppt)

The above precipitation reaction is also a double displacement reaction as both reactants exchange their ions to form new products.
