10
Q
Melting/boiling point? Why?
A
High melting and boiling point. Because of ionic bonding and existing in giant ionic lattice. Lots of energy is needed to break the strong electrostatic attraction between the positive and negatively charged ions.
11
Q
Conductor of electricity? Why?
A
Cannot conduct electricity when solid because ions are not free to move. Good conductor when molten or aqueous because ions are free to move
12
Q
Soluble?
A
Yes
13
Q
Oxidation
A
the loss of electrons
14
Q
Reduction
A
the gain of electrons
15
Q
in what states of matter can ions exist?
A
solid, molten, aqueous. NOT LIQUID
