$Be^{2+}$

Vedclass · Answer

(D) The heat of hydration is inversely proportional to the ionic radius and directly proportional to the charge density of the ion.$Be^{2+}$ has the smallest ionic radius and the highest charge among the given options,resulting in the highest charge density.Therefore,the order of decreasing heat of hydration is: $Be^{2+} > Li^{+} > Ba^{2+} > K^{+}$.Thus,$Be^{2+}$ has the largest heat of hydration.

Which of the following ions has the largest heat of hydration?
