Question

aqueous solution of sodium chloride sodium sulphate and calcium chloride are taken in three separate test tubes using aqueous Barium Chloride how do you identify sodium sulphate​

Answer 1

Answer:

The onle having sodium sulphate will cause displacement reaction and a white precipitate is formed. That test tube with white precipitate will be sodium sulphate

Answer 2

Answer:

• For the given compounds that we see in the question the compound that is form would be insoluble and hence will form a precipitate this kind of reaction is called precipitation reaction.
• When sodium chloride, Barium sulphate and Calcium chloride are mixed together then the reaction happens and barium Chloride is formed with in a form of a white precipitate lying below.
• Hence the remaining compound in test tube would be sodium sulphate.
• We can say clearly that the aqua solution remaining is sodium sulphate because Barium Chloride forms the precipitate and does not mix with the solution.
