Question

When sodium sulphate solution reacts with barium chloride solution, the solution after the reaction contains mainly
1) barium sulphate
2) sodium chloride
3) a and b both
4) none of a and b

Answer 1

2) SODIUM CHLORIDE

In aqueous solution:

BaCl2 (aq) + Na2SO4 (aq) --> 2 NaCl (aq) + BaSO4 (s)

Barium sulfate is insoluble in water, so it will precipitate as a solid.

Sodium chloride will remain in solution.

Answer 2

Both a and b :

When sodium sulphate reacts with barium chloride, barium sulphate and sodium chloride is formed
