4
Q
What does lattice structure have?
A
A regular arrangement , ionic bonds between oppositely charged ions
5
Q
Are ionic compounds soluble?
A
Yes
6
Q
State why sodium chloride does not conduct electricity when it is in solid state
A
The ions are not free to move around in a solid
7
Q
Explain why sodium chloride does conduct electricity when it is molten or aqueous solution
A
The ions are free to move around when sodium chloride is liquid or when it is dissolved in water. This means they can carry electric charge from place to place
