c) Barium chloride is mixed withsodium sulphate solution
d) Barium carbonate is mixed with sodium sulphate solution

please tell me answer fast it is urgent and don't give irrelevant answer please......​

Answer 1

Answer:

ANSWER

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

Na

2

SO

4

+BaCl

2

⟶2NaCl+BaSO

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
