Question

In a double displacement reaction such as the reaction between sodium sulphate solution and barium chloride solution: (i) exchange of atoms takes place (ii) exchange of ions takes place (iii) a precipitate is produced (iv) an insoluble salt is produced The correct option is: (a) (ii) and (iv) (b) (i) and (iii) (C) only (ii) (d) (ii), (iii) and (iv)​

Answer 1

Answer:

(d) (ii), (iii) and (iv)​

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 (aq)→  (insoluble) BaSO4 (s) ↓+2NaCl(aq)

Here, exchange of ions takes place.

All the best...
