The heat of hydration decreases with the increase in:
Correct answer: B. Size of cations
- A. Number of neutrons
- B. Size of cations
- C. Size of atomic radii
- D. Number of electrons
Explanation
Explanation:As cation radius increases, charge density decreases, thus heat of hydration decreases.This option is not correct because the number of neutrons does not affect the charge or size of the ion, which are the primary factors that determine the heat of hydration. This option is also incorrect because the size of atomic radii is not directly related to the size or charge of the ion. This option is also incorrect because the number of electrons does not directly affect the size of charge of the ion.

About Lattice Energy
Lattice energy describes the energy released when gaseous ions form one mole of an ionic solid, or the energy required to separate that solid into gaseous ions, depending on the convention used. Its value depends mainly on ionic charge and radius and is calculated through Born-Haber cycles.
