    Question # 1

    Define "heat of solution" and "hydration energy"?

    • Ans 1: The quantity of heat energy that is absorbed or released when a substance forms solution, is termed as heat of solution.
      When ionic compound is dissolved in water, the first step is the separation of ions from solid and second step is separated ions are surrounded by solvent molecules.A Hydrated ion is attracted by the solvent dipoles and energy is released, so second step is exothermic. The energy given out by the second step is known as the hydration energy .
