Solution 1
It seems like there was a mistake in your request. Could you please provide the specific question you want me to answer?
Solution 2
It seems like you've pasted a series of questions but they are not clearly separated. I'll do my best to answer them:
-
The types of compounds that can be broken down by electrolysis are molten or aqueous ionic compounds. Solid ionic compounds can also be broken down by electrolysis, but it requires a lot of energy.
-
Ionic compounds are formed from a metal and a non-metal.
-
In electrolysis, the name of the positive electrode is the anode.
-
During the electrolysis of sodium chloride solution, chlorine is formed at the anode.
-
During the electrolysis of molten lead bromide, positive lead ions gain electrons to form lead atoms at the cathode.
-
During the electrolysis of molten lead bromide, negative bromide ions lose electrons to form bromine molecules at the anode.
