chemical reactions - introducing electrolysis

Question 1

do solid ionic compounds conduct electricity? why?

Answer 1

no because the ions are locked in place so are not free to move. they are held in place by strong electrostatic forces of attraction

Question 2

can molten ionic compounds conduct electricity? why?

Answer 2

yes because the forces of attraction have been broken and the ions are free to move

Question 3

what are the liquids or solutions that can conduct electricity called?

Answer 3

electrolyte

Question 4

what does molten mean?

Answer 4

melted

Question 5

what are electrolysis conductors made out of?

Answer 5

graphite or metal

Question 6

what is the positive electrode?

Answer 6

anode

Question 7

what is the negative electrode?

Answer 7

cathode

Question 8

what does the cathode have? what does the anode have?

Answer 8

cathode - covered in electrons
anode - lack of electrons

Question 9

For the ionic compounds of lead bromide PbBr, what would happen during electrolysis?

Answer 9

the Pb positive 2 plus ion would be attracted to the cathode due to opposite charges attracting. The lead ion would then gain 2 electrons to form lead atoms. This is an reduction reaction.
The Br negative ions would be attracted to the anode and would lose on electron to form bromide atoms. This is an oxidation reaction. However, bromide is a diatomic molecule.
