HYDRATION ENERGY AND RADII OF HYDRATED ION + ELECTRICAL CONDUCTIVITY IN AQUEOUS SOLUTION

BY HYDRATION:

ENTHALPY OF SOLUTION, ENTHALPY OF NEUTRALIZATION AND ENTHALPY OF HYDRATION

Application OF Hydration Energy || Solubility OF Ionic Compounds

Which statement is/are correct(more than one correct) ? (a) In aqueous solution A1 gives hydrated ions [A1(H_(2)O)_(6)]^(3+) (b) Most of aluminium compounds are covalent because formation of A1^(3+) requires much more energy (=5138 kJ mo1^(-1)) which is not available ordinarily (c ) In aqueous solution A1 forms hydrated ions becuse og high (negative) heat of hydration of A1^(3+) compensates the high IE_(3) of A1 (d) Magnitude of hydration energy of A1^(3+)lt IE_(3) of A1 .

The ion which has the maximum value of hydration energy is

The radius of which hydrated ion is largest

The hydration entahphy of Mg^(2+) ion is higer than that of

The hydration energy of Mg^(2+) is lower than that of-
