Electrolysis

Question 1

Electrolytes:

Under these conditions the
ions in electrolytes are free to:

Answer 1

are ionic compounds that are:
in the molten state (heated so they become liquids), or dissolved
in water

move within the liquid or solution.

Question 2

Electrolysis is a process in which:

Answer 2

electrical energy, from a
direct current
(dc) supply, breaks down electrolytes. The free moving ions in electrolytes are attracted to the oppositely charged
electrodes which connect to the dc supply.

Question 3

When ions reach an electrode, they gain or lose electrons .As a result, they form atoms or
molecules of elements :

positive ions gain electrons from the ——— charged ———–
negative ions lose electrons at the ——— charged ———

Answer 3

negatively
cathode
positively
anode
