#C3.3.1
describe electrolysis in terms of the ions present and reactions at the electrodes
#C3.3.2
predict the products of electrolysis of binary ionic compounds in the molten state
#C3.3.3
recall that metals (or hydrogen) are formed at the cathode and non-metals are formed at the anode in electrolysis using inert electrodes
#C3.3.4
use the names and symbols of common elements and compounds and the principle of conservation of mass to write half equations
#C3.3.5
explain reduction and oxidation in terms of gain or loss of electrons, identifying which species are oxidised and which are reduced
#C3.3.6
explain how electrolysis is used to extract some metals from their ores including the extraction of aluminium
#C3.3.7
describe competing reactions in the electrolysis of aqueous solutions of ionic compounds in terms of the different species present, including the formation of oxygen, chlorine and the discharge of metals or hydrogen linked to their relative reactivity
#C3.3.8
describe the technique of electrolysis of an aqueous solution of a salt
