Chemistry 4.04: Properties of Ionic Compounds

How does dissolving an ionic compound in water increase electrical conductivity?

The water molecules electrostatically interact with the ions in the crystal and let the ions move freely.

Which statement explains why ionic compounds are brittle?

When a force is applied to the crystal, the strong electrostatic interactions cause similar ions to repel and shatter the crystal lattice.

Why do ionic compounds have high melting points?

The strong electrostatic interactions between ions require a lot of energy to break the bonds.

Which property is a characteristic of an ionic compound?

high melting point

Which compound would have the lowest melting point?

sucrose
