C2 : Properties of Ionic Compounds Flashcards
1
Q
Why do Giant Ionic Compounds have high melting / boiling points
A
Because the electrostatic forces require a lot of energy to break
2
Q
Why cant Ionic Compounds conduct electricity when solids
A
Because the ions can’t move as they’re locked by the electro static forces
3
Q
Why can giant ionic lattices conduct electricity when they are melted or dissolved in water
A
The ions are free to move and carry the charge
4
Q
What is a Giant Ionic Lattice
A
Giant structures where positive ions are surrounded by negative ions
