1. What type of structure do all ionic compounds have?

a) Simple molecular
b) Giant covalent structure
c) Giant ionic lattice
d) Giant metallic structure

2. Why do solid ionic compounds not conduct electricity?

a) They have no free electrons
b) The ions are held in fixed positions and cannot move
c) They have weak ionic bonds
d) They have strong ionic bonds

3. What happens to the lattice structure when an ionic compound dissolves in water?

a) It remains intact
b) It becomes a giant covalent structure
c) The ions gain electrons and become neutral atoms
d) The water molecules pull apart the lattice structure allowing the ions to move freely

4. Solutions which conduct electricity are called .

5. What happens to the ions in a molten ionic compound that allows it to conduct electricity?

a) They become free to move
b) They lose electrons and form atoms
c) They gain electrons and become neutral atoms
d) They form small molecules

6. Ionic compounds are brittle because if the layers of move then ions with the same will come into contact and repel each other causing a fracture in the lattice structure.

7. Which of the following leads to an increase in the melting points of ionic compounds?

a) Larger charges on the ions and smaller ions
b) Smaller ions and smaller charges on them
c) Larger charges on the ions and larger ions
d) Smaller charges on the ions and smaller ions

8. Which of the following is soluble?

a) Lead iodide
b) All group 1 metal salts
c) All group 7 metal salts
d) Calcium hydroxide

9. What does the phrase "like dissolves like mean"?

a) Ionic compounds will dissolve in covalent solvents such as oil and hexane
b) Water will dissolve on covalent solvents
c) Water can dissolve some ionic substances
d) Ionic substances dissolve in non-polar solvents

10. What happens at the cathode during the electrolysis of copper(II) chromate solution?

a) Blue copper (II) ions migrate to the cathode and are deposited as brown copper atoms
b) Yellow chromate ions are reduced to form oxygen gas and bubbles are seen
c) Water molecules are decomposed releasing bubbles of oxygen gas
d) The cathode slowly dissolves
