Which of the following salts, Li2SO4 or Cs2SO4, is expected to have the more exothermic enthalpy of hydration?

Interpretation Introduction

Interpretation: From the following, which pairs have more exothermic hydration energy has to be identified.

Concept Introduction:

Enthalpy of hydration is the enthalpy of solvation of ions.

The value of enthalpy of hydration depends on

  • Charge of the ion
  • Distance between the center of ion and the oppositely charged end of the water dipole.

Explanation of Solution

The size of Li+ is smaller comparing to Cs+ ion and thus water molecules can easily approach the ion
