Why is the melting point of sodium chloride high?

Answer 1

Sodium chloride has a high melting point for a few reasons. Sodium chloride is held together by ionic bonds, and ionic bonds are very strong (as compared to covalent bonds, which are relatively weak). The higher the bonding strength, the more heat it will take to break those bonds to create a liquid.

Thus, sodium chloride has a high melting point because of the strong ionic bonds it has.

Answer 2

Because NaCl is an ionic compound.

NaCl is formed by sodium and chloride ions. Unlike covalent bonds, these are electrostatic ionic bonds. It requires a massive amount of energy to break them.

Answer 3

Because NaCl is an ionic compound.

Sodium chloride is formed by sodium and chloride ions. These ions attract each other alternatively by electrostatic ionic bonds. It requires a tremendous energy to break them.

Answer 4

sodium chloride has high melting point because the sodium chloride is an ionic bond. As ionic bond is very strong it will take more heat to break those bonds to create liquid

Answer 5

It takes a significant amount of energy - in this case derived from the external temperature - to overcome the strong bonds between the atoms of sodium and chlorine.

Answer 6

It is a ionic compound. Generally ionic compounds have high melting points.

Answer 7

NaCl is formed by sodium and chloride ions. Unlike covalent bonds, these are electrostatic ionic bonds. It requires a massive amount of energy to break them.

Answer 8

Sodium chloride is formed by sodium and chloride ions. These ions attract each other alternatively by electrostatic ionic bonds. It requires a tremendous energy to break them.

Answer 9

These two compounds have a very strong ionic bond.

Answer 10

Ionic compounds have higher melting points, the bonds are stronger.
