Question

In a double displacement reaction such as the reaction with between sodium sulphate solution and barium chloride solution :
(A) exchange of atoms takes place
(B) exchange of ions take place
(C) a precipitate is produced
(D) an insoluble salt is produced

The correct option is
(a) (B) and (D)
(b) (A) and (C)
(c) only(B)
(d) (B),(C) and (D)

Give reaction also​

Answer 1

Explanation:

The correct option is (d) (B), (C) and (D). Sodium sulphate chemically reacts with barium chloride in the form of their aqueous solution to form a white precipitate of barium sulphate. This is a double displacement reaction in which sulphate ions are displaced by chloride ions and vice-versa.

Answer 2

Answer:

(d) BaSO4 is a white precipitate i.e. an insoluble salt.

NaSO4 + BaCl2 ──⟩ BaSO4↓ + 2NaCl
