aqueous solution of sodium chloride sodium sulphate and calcium chloride are taken in three separate test tubes using aqueous washing how do you identify sodium sulphate |
|
Answer» ong>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 Explanation: 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. |
