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

Answer:

Option (d) = (B), (C) and (D)

Explanation:

When sodium sulphate reacts with barium chloride solution, barium sulphate which is an insoluble product (i.e., precipitate) and sodium chloride are formed.

Na2 SO4+  (aq)+BaCl2 →  (insoluble) BaSO4 ↓+2NaCl(aq)

Here, exchange of ions takes place.

Hence, option D is correct.

Answer 2

Answer:

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

NaSO4 + BaCl2 ──⟩ BaSO4↓ + 2NaCl
