Ionic Compounds Flashcards
What do ionic compounds always have?
A giant ionic lattice structure.
How strong are the electrostatic forces of attraction in giant ionic lattices?
There are very strong electrostatic forces of attraction between oppositely charged ions, in all directions.
What are the melting and boiling points like in ionic compounds?
Ionic compounds have high melting and boiling points.
Why do ionic compounds have high melting and boiling points?
There is a strong attraction between the ions, and it takes a large amount of energy to overcome this attraction.
Do solid ionic compounds conduct electricity?
No, because the ions are fixed in place and can’t move.
Can melted ionic compounds conduct electricity?
Yes, because the ions are free to move and will carry an electric current.
Can ionic compounds dissolve in water?
Yes, most ionic compounds can dissolve in water.
Can dissolved ionic compounds conduct electricity?
Yes, because the ions separate and are all free to move in the solution, so they can carry an electric current.
