Electrolysis

Question	Answer
What is electrolysis	The breaking down of a compound using an electric current
What kind of compound only works with electrolysis.	Ionic compounds, when they are molten or dissolved in water because they only conduct electricity in that state
What is an anode, cathode, electrode and electrolyte?	Electrolyte: a compound that conducts electricity when molten and breaks down during electrolysis. Electrode: rods that carry the electric current to and from the electrolyte. Anode: +electrode Cathode: -electrode
What is an inert electrode?	An electrode that does not react during electrolysis
Why are electrodes normally made from inert conductors?	So that the electrodes do not react with the electrolyte or the products of the electrolysis.
Explanation for electrolysis with lead bromide.	-carried out in fume cupboard because bromine is toxic and corrosive -lead bromide is heated, begins to melt and the lamp lights up -which shows an electric current is flowing, and ions in electrolyte are moving. -electric current decomposes the lead bromide. -grey beads of molten lead form at cathode -reddish brownish gas formed at anode.
