In chemistry, hydration energy (also hydration enthalpy) is the amount of energy released when one mole of ions undergoes hydration. Hydration energy is one component in the quantitative analysis of solvation. It is a particular special case of water. The value of hydration energies is one of the most challenging aspects of structural prediction. Upon dissolving a salt in water, the cations and anions interact with the positive and negative dipoles of the water. The trade-off of these interacti… WebThe answer is the option (iii) Hydration enthalpy is a measure of the tendency of an element to lose an electron in aqueous solution. More negative the hydration enthalpy, greater is the ability to lose an electron, making it a strong reducing agent.
