What are the characteristic of most ionic compounds?

Answer 1

High boiling/melting points.

Very hard.

They can conduct electricity when molten or dissolved.

EXPLANATION: High boiling/melting points - they form lattices held together by electrostatic forces of attraction which stretches not only to the atom they reacted with but to all the ions in the lattice, which makes it hard to break.

Very hard - lattice is a regular structure. Also see above.

They can conduct electricity when molten or dissolved - the ions are positively and negatively charged but stuck in fixed positions when a solid. When molten or dissolved, the ions are free to move around and therefore carry the charge so conduct electricity.

Answer 2

• The form positive and negative ions when they dissolve in water
• They conduct electricity in their molten state
• They conduct electricity when dissolved in water
• They are formed from a metal and a non-metal
• They form crystal lattices that have a characteristic shape of the ionic compound
• They are held together by electrostatic interaction
• They typically have high melting points

Answer 3

1. ionic compounds are neutral as a whole although they are formed by the oppositely charged ions.

2. They have very high melting and boiling points.

3. In solid state these compounds from ionic compounds from ionic crystals. sodium chloride is an example of such ionic crystals.

4. such compounds are quite often, soluble in water but in soluble in non aqueous solvents like petrol or kerosene oil.
