Lithium and beryllium, the first members of alkali metals group and alkaline earth metals group, show anomalous behaviour due to the small sizes of their atoms and ions, high ionisation enthalpies, high polarizing power and absence of vacant d-orbitals in their valence shell. Lithium resembles magnesium while beryllium resembles aluminium due to diagonal relationships. How will you distinguish between BaSO_4 and BeSO_4 ?

1.	Lithium and beryllium, the first members of alkali metals group and alkaline earth metals group, show anomalous behaviour due to the small sizes of their atoms and ions, high ionisation enthalpies, high polarizing power and absence of vacant d-orbitals in their valence shell. Lithium resembles magnesium while beryllium resembles aluminium due to diagonal relationships. How will you distinguish between BaSO_4 and BeSO_4 ?
Answer» SOLUTION :`BaSO_4` is insolublein WATER but `BeSO_4` is SOLUBLEIN water
