1
Q
Why do ionic compounds have high melting and boiling points?
A
There are many strong bonds between the ions which takes a lot of energy to overcome this attraction.
2
Q
Can they conduct electricity? When?
A
Yes only when they are molten as the ions are now free to move.
3
Q
How do ionic compounds conduct electricity
A
The ions separate and are free to move in the solution so they’ll carry electric current.
