Web11 jul. 2024 · Hydration enthalpy, also known as hydration energy, is always negative. Hence, the trend in the group 2 hydration enthalpy is: Be2+>Mg2+>Ca2+>Ba2+>Ra2+ Because alkaline earth metal ions are smaller in size than alkali metal ions, their … WebBarium is a Group 2 and Period 6 element This means that the Mg 2+ ion is smaller than the Ba 2+ ion The attraction is therefore much stronger for the Mg 2+ ion As a result, the standard enthalpy of hydration of MgSO 4 is more exothermic than that of BaSO 4 Ionic charge Δ Hhydꝋ is more exothermic for ions with larger ionic charges
