1
Q
What is an example of a simple ionic compound?
A
- lead bromide
2
Q
How is a simple ionic compound is electrolysed in the molten state?
A
- inert electrodes
3
Q
What happens when a simple ionic compound is electrolysed in the molten state?
A
- metal (lead) is produced at cathode
- non-metal (bromine) is produced at anode
4
Q
Why is a metal produced at a cathode?
A
- the metal is the positive ion
5
Q
Why is a non-metal produced at anode?
A
- the non-metal is the negative ion
