Vedclass · Answer

(A) Statement-$I$ is correct: The solubility of alkaline earth metal sulfates decreases down the group. $BeSO_4$ and $MgSO_4$ have high hydration enthalpies which overcome the lattice enthalpy,making them readily soluble in water.Statement-$II$ is correct: Alkaline earth metal nitrates decompose on heating. $Be(NO_3)_2$ decomposes to give $BeO$,$NO_2$,and $O_2$. Other nitrates like $Ca(NO_3)_2$,$Sr(NO_3)_2$,and $Ba(NO_3)_2$ decompose to form their respective nitrites $(M(NO_2)_2)$ and $O_2$.

Consider the following statements:
Statement-$I$: Both $BeSO_4$ and $MgSO_4$ are readily soluble in water.
Statement-$II$: Among the nitrates of alkaline earth metals,only $Be(NO_3)_2$ on strong heating gives its oxide,$NO_2$,and $O_2$.
