Properties Of Ionic Compounds Flashcards
1
Q
Sodium chloride e.g
A
White crystal
Solid
High melting point
Soluble
Conducts electricity as a solution but not solid
2
Q
What kind of structures do ionic compounds form
A
Giant structures where every positive ion is surrounded by a negative ion
3
Q
Why do ionic compounds have high melting and boiling points ?
A
The strong electrostatic attraction means they can’t move further apart and require a lot of energy to break
4
Q
Why can’t ionic compounds conduct electricity as solids?
A
The ions can’t move due to strong electrostatic forces of attraction and being locked in lattice.
5
Q
Why do ionic compounds conduct electricity as a solution ?
A
Because the ions can move
6
Q
Why are ionic compounds soluble?
A
The ions can separate in water
