The hydration of an ion is always negative. This is because ion and water attractions are only formed when the ion is surrounded by water, deeming it negatively charged.

Why does lithium have a stronger ion-dipole interaction with water?
because it has more negative enthalpy of hydration
What is hydration of ion in aqueous solution?
The water molecules surround the negative ions and positive ions and pull them away into the solution. This process is called dissociation
What significant intermolecular forces is involved between sodium ion and water?
Water molecules surround the sodium ion- the negative end of the water pointing towards the sodium ion. the attraction is electrostatic. The bond is weak- the effect is a hydration sphere of water where the water molecules drift in and drift out.
What is an example of a negative ion?
A positive ion is an ion with no negative charges.
Does flurine form a positive or negative ion?
Fluorine is negative and will produce a negative ion.
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 charge of an ion?
either negative or positive charge always
What is hydration of ion in aqueous solution?
The water molecules surround the negative ions and positive ions and pull them away into the solution. This process is called dissociation
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 the standard enthalpy change of neutralization between hydrofluoric acid and sodium hydroxide more negative than usual?
Because of high of heat of Hydration of HF ( Fluoride ion is extensively hydrated because of it's small size )
What significant intermolecular forces is involved between sodium ion and water?
Water molecules surround the sodium ion- the negative end of the water pointing towards the sodium ion. the attraction is electrostatic. The bond is weak- the effect is a hydration sphere of water where the water molecules drift in and drift out.
Does chlorine form a positive or a negative ion?
Negative ion. Cl-
What is positive ion and negative ion in NACl?
Na is positive ion,Cl is negative ion
What is an example of a negative ion?
A positive ion is an ion with no negative charges.
Does flurine form a positive or negative ion?
Fluorine is negative and will produce a negative ion.
What is a positive and negative ion?
when an atom loose electron it become negative ion and when it gains electron it become positive ion
