Hydration energy (also hydration enthalpy) is the amount of energy released when one mole of ions undergo hydration. It is a special case of dissolution energy, with the solvent being water.

What is relation between hydration energy lattice energy and enthalpy of solution?
enthalpy change of solution=enthalpy change of hydration - enthalpy change of lattice
Why hydration energy decreases from top to bottom in group 1-a and increases from left to right in a period?
Hydration Energy Increases Significantly By Moving From Left To Right In A Period As The Charge To Size Ratio Increases.
Heat of Hydration trend in p-block elements?
Larger the atomic size lesser the hydration energy or the energy decreases. As the atomic sizes decrease from left to right in a periodic table therefore the heat of hydration increases from left to right. Same is the case with p-block elements .
Which alkali metal has lowest ionic mobility in water?
Lithium will have least ionic mobility as it has the greatest hydration energy.
Why hydration is always called solvation but solvation is not always called hydration?
It depends on what the solvent is. If it is water, then it is called hydration. If the solvent is not water, then it cannot be called hydration.
Why is sodium nitrate more soluble than potassium nitrate?
Yes. Because hydration energy of Na+ is greater than K+. More the hydration energy greater is solubility. A compound is soluble if hydration energy is greater than lattice energy.
What is relation between hydration energy lattice energy and enthalpy of solution?
enthalpy change of solution=enthalpy change of hydration - enthalpy change of lattice
How does hydration energy vary along a group?

What is the significance of high hydration enthalpy?
Enthalpy of hydration is the energy change for converting 1 mol of an anhydrous substance to 1 mol of the hydrated substance. More the hydration enthalpy more will be the energy released on getting hydrated. The stability of any species is inversely proportional to the energy content and any chemical species tends to becoming more and more stable. Thus having high hydration enthalpy means it will become more stable on hydration and thus it will tend to forming its hydrate.

What does it mean when an ion from a salt forms a hydration sphere?
There has been a change in energy.
Why HF has high neutralization enthalpy?
Because of high value of hydration energy.
Are energy drink good hydration?
No, energy drinks are actually not good to drink when you are thirsty because they do not hydrate you like water does.
What is the equation of heat of hydration?
Heat of hydration or enthalpy of hydration of ions corresponds to the heat that is released by hydration of one mole of ions at a constant pressure. The more the ion is hydrated, the more heat is released. Degree of hydration depends on the size and charge of ion. The smaller the ion and the greater its charge, it will be the more hydrated.
What is meant by conservation of energy?
It is meant to transfer energy from one form to another.
Why heat is evolved while adding water to sodium hydroxide?
This is called hydration energy (heat).
