Vedclass · Answer

(D) All the given statements are correct:$(i)$ Beryllium oxide $(BeO)$ is amphoteric,meaning it reacts with both acids and bases.$(ii)$ Group $II$ elements dissolve in liquid ammonia to form deep blue-black solutions due to the presence of ammoniated electrons,which absorb energy in the visible region.$(iii)$ Hydration enthalpy is inversely proportional to the size of the ion. As the size of the cation increases from $Be^{2+}$ to $Ba^{2+}$,the hydration enthalpy decreases.

Identify correct statements from the following:
$i$. Beryllium oxide is an amphoteric oxide.
$ii$. Group $II$ elements dissolve in liquid ammonia to form deep blue-black solutions.
$iii$. The hydration enthalpy of group $II$ ions decreases from $Be^{2+}$ to $Ba^{2+}$.
