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

`MgCl_(2), NaHCO_(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 that is `Na_(2)CO_(3)` to form `MgCO_(3)` and `Na_(2)SO_(4)`

A mixture of two components X and Y. X is an element and Y is a compound of two non metals. Identify X and Y.

When a metal X is treated with cold water, it gives a basic salt Y with molecular formula XOH (Molecular mass=40) and liberates a gas Z which easily catches fire. Identify X,Y and Z and also write the reaction involved.
