Ionic Bonding - Properties of Ionic Compounds

The properties of Ionic Compounds are directly related to their structure. The strong electrostatic attraction being cations and anions makes the compounds solid and hard with high melting points. When a force is applied, the like-charges align and repel each other and this causes ionic compounds to be brittle. Ionic solids are unable to conduct electricity because the ions are in fixed positions; however, as a liquid or in solution, the ions are free to move and conduct electricity.

because water is polar, and when an ionic compound such as NaCl is placed in water, each Na+ ion is pulled away from the crystalline structure formed by the ionic bonding of the sodium and chlorine atoms by the negative side of the polar water molecules, while Cl- ions are also pulled away by the positive pole of the water molecules. Each ion is then surrounded by a cluster of water molecules. This is what causes ionic compounds to dissolve in water.

you gotta a beautiful accent. Thanks for the video :)

But if ionic compounds have high melting points then why do they dissolve in water?

Sir my question is why do ionic compounds usually hard?? But I totally confused in these answer is not in these

I don't understand, you talk about ions being solid and hard but then you talk about liquids???
