What is the correct order of hydration energy?

Na+>Mg+2.

Which of the ions have maximum hydration energy?

Hydration energy is large for the ion having smaller size and higher charge. Here Mg2+ ion is the smallest and has +2 charge, hence its hydration will be the highest.

What is hydration energy dependent on?

Hydration energy depends on charge of ion and ionic radius. Higher the charge, greater the hydration energy.

Why does hydration energy increase left to right in a period?

Hydration Energy significantly by moving from left to right in a period as the charge to size ratio increases, as found in the metal ions of the third period.

Which of the following has lowest value of hydration enthalpy?

Lithium ion
“Lithium ion has the smallest hydration enthalpy of all the alkali metals.”

Which of the following has highest hydration energy mgcl2 cacl2 bacl2 srcl2?

Answer is option a The hydration energy of M2+ ion decreases with increase in ionic radii And in group ionic radius increases as go down the group. Mg+2 have lowest ionic radii hence higher hydration energy .

Which of the following set will have highest hydration enthalpy and highest ionic radius?

Smaller the size, greater is the hydration enthalpy. So, Li will have highest hydration enthalpy. Down the group ionic radius increases, so Rb will have highest ionic radius.

Which one has maximum degree of hydration?

The smaller the scale created by the cation, the higher the degree of hydration. As lithium is the smallest (in size) of all alkali metals, the highest hydration energy of all alkali metals is considered to have.

What is hydration energy how it varies in periodic table?

The size of the hydration enthalpy is governed by the amount of attraction between the ions and the water molecules. The attractions are stronger the smaller the ion. For example, hydration enthalpies fall as you go down a group in the Periodic Table. In both groups, hydration enthalpy falls as the ions get bigger.
