Question

MCQ

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

Options

• (B) and (D)

• (A) and (C)

• only (B)

• (B), (C) and (D)

Solution

$\ce{\underset{\text{Sodium sulphate}}{Na2SO4(aq)}+\underset{\text{Barium Chloride}}{BaCl2(aq)}->\underset{\text{Barium Sulphate}}{BaSO4(s)}+\underset{\text{Sodium Chloride}}{2NaCl(aq)}}$

The white precipitate of BaSO4 is formed by the reaction of "SO"_4^(2-) and Ba2+.

Hence, the correct answer is the (B), (C), and (D).
