Water-containing salt X, of a divalent metal, when treated with a compound Y gives much lather with soap. Further, an insoluble compound `MgCO_(3)` and salt of a monovalent metal sulphate are formed. Identify X and Y, respectively.

A

`CaCl_(2),Na_(2)CO_(3)`

B

`MgSO_(4),Na_(2)CO_(3)`

C

`MgClNaHCO_(3)`

D

`CaSO_(4),Mg(HCO_(3))_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Divalent metal salt X, i.e., `MgSO_(4)` is treated with compound Y, i.e., `Na_(2)CO_(3)` to form `MgCO_(3) and Na_(2)SO_(4)`.
`MgSO_(4)+Na_(2)CO_(3)toMgCO_(3)+Na_(2)SO_(4)`
