Solubility of an ionic compound in water...

Solubility of an ionic compound in water is mainly dependent on:
a.Lattice enthalpy , b. Hydration enthalphy
Both these factors oppose each other and the resultant of these determines the solubility of an ionic compound in water. If lattce enthalpy has greater value, the compound is less soluble.
In case hydration enthalpy has greater value, the compound is
highly soluble in water.
Which of the following is more soluble in water?

A

`MgSO_(4)`

B

`CaSO_(4)`

C

`SrSO_(4)`

D

`BaSO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
Lattice enthalpy decreases less rapidly as compared to hydration enthalpy in case of alkaline earth metal sulphates.
