7
Q
What are the 3 properties of ionic compounds
A
-Dissolve in water (as water molecules are polar they can attract the positive and negative ions and break down the structure)
-Conduct electricity when molten or dissolved in water (bc ions are free to move and carry charge)
-High melting point (bc there are many strong electrostatic forces and therefore lots of energy is needed to overcome them)
