A solution of a compound X in dilute HCl on treatment with a solution

1.	A solution of a compound X in dilute HCl on treatment with a solution of BaCl_(2) gives a white precipitate of compound Y which is insoluble in conc. HNO_(3) and and conc. HCl. Compound X imparts golden yellow colour to the flame. underset(("immparts golden yellow colour"))(X("Solution in dilute HCl"))+BaCl_(2) to underset("White")(Y)underset("Conc. HCl")overset("Conc. "HNO_(3))toInsoluble What are compounds X and Y?
Answer» X is `MgCl_(2)` and Y is `BaSO_(4)` X is `CaCl_(2) and Y` is `BaSO_(4)` X is `Na_(2)SO_(4)` and Y is `BaSO_(4)` X is `MgSO_(4)` and Y is `BaSO_(4)` Solution :`underset((X))(Na_(2)SO_(4))+BaCl_(2) to underset((Y))(BaSO_(4))+2NaCl`
