Question

When sodium sulphate solution reacts with barium chloride solution, the solution after the reaction contains mainly.....

• A. barium sulphate
• B. sodium chloride
• C. a and b both
• D. none of a and b

Answer 1

The correct option is B sodium chloride

When sodium sulphate solution reacts with barium chloride solution results in double displacement reaction in which ions are exchanged.

$N{a}_{2}S{O}_4+BaC{l}_2⟶2NaCl+BaS{O}_4$

In this reaction barium sulphate and sodium chloride are formed,the solution in water consists only sodium chloride because sodium chloride dissolves in water while barium sulphate it settles down and a white precipitate is formed (insoluble).

Hence, option B is correct.
