A level chem Properties of ionic compounds

In an ionic lattice what are the ions attracted to?

Oppositely charged ions

What type of force acts between ions of opposite charges?

Electrostatic forces of attraction

What are the three properties of a giant ionic lattice?

• Very high melting and boiling points

• They tend to be soluble in solvents

• They do NOT conduct electricity when solid

Why do ionic compounds have high melting points?

Because of the strong electrostatic forces there needs to be a lot of energy to overcome the forces

Why are ionic compounds soluble in polar solvents?

When the ionic compound gets dissolved in a polar solvent the molecules in the solvent surround the ion.

What impact do the solvent molecules have when surrounding ions in an ionic compound?

The molecules can overcome the electrostatic attraction between the ions.

How can the solubility of an ionic compound decrease?

When the charges of the ions increase

Why cant ionic compound conduct electricity?

Because the ions in the compound are locked in place by the electrostatic attractionsWhat

What is one requirement for a solid to conduct electricity?

The ions need to be able to move around to carry the charge

How can ionic compound conduct electricity?

They need to be molten or in a solution

Why can ionic compounds conduct electricity in a solution?

Because the ions are free to move
