Question:
Consider the following:
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$_2$.
The correct answer is
Consider the following:
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$_2$.
The correct answer is
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$_2$.
The correct answer is
Show Hint
BeSO$_4$ and MgSO$_4$ are soluble. All alkaline earth nitrates decompose to oxides, NO$_2$, and O$_2$ on heating.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Statement I: BeSO$_4$ and MgSO$_4$ are readily soluble in water due to the high hydration enthalpy of the smaller Be$^{2+}$ and Mg$^{2+}$ ions, which overcomes their lattice enthalpy. This statement is correct. Statement II: All nitrates of alkaline earth metals decompose on heating to give their corresponding oxides, NO$_2$, and O$_2$. So, this statement is incorrect. It's not exclusive to Be(NO$_3$)$_2$.
