A metal M readily forms its sulphate MSO...

A metal M readily forms its sulphate `MSO_(4)` which is water soluble. It forms oxide `MO` which becomes inert on heating. It forms insoluble hydroxide which is soluble in `NaOH`. The metal `M` is:

A

`Mg`

B

`Ba`

C

`Ca`

D

`Be`

Text Solution

Verified by Experts

The correct Answer is:
D
`BeSO_(4)` and `MgSO_(4)` are soluble in water. Only `BeO` is amphoteric and thus, reacts with `NaOH`.

A metal M readily forms its sulphate MSO_(4) which is watersoluble. It forms its oxide MO which becomes inert on heating. It forms its insoulbe hydroxide M(OH)_(2) which is soluble in NaOH solution. Then M is

The solubility of a crystalline compound in water is influenced by two factors. These are lattice enthalpy and hydration enthalpy. Lattice enthalpy is needed to separate the ions from the crystal lattice. At the same time hydration enthalpy is released when the ion are dissolved in water. The resultant of these two opposing tendencies guides the solubility of the compound in water. If lattice enthalpy has a greater magnitude, the compound has low solubility. In case hydration enthalpy is more, then the compound is highly soluble in water.
