What is an anode?
An anode is a positive electrode rod made of graphite (carbon) that attracts negative ions
What is a cathode?
A cathode is a negative electrode rod made of graphite (carbon) that attracts positive ions
What are electrodes?
Electrodes are rods made of graphite (carbon) that allows for the electrical flow to attract ions
What is a cation?
A cation is a positively charged ion that is attracted to an anode
What is an anion?
An anion is a negatively charged ion that is attracted to a cathode
What is an electrolyte?
An electrolyte is a solution with an ionic compound containing positive and negative ions
What is an ore?
An ore is a rock that contains a metal that can be extracted
What is extraction
extraction is where you separate a metal from its ore, this can be done through the process of electrolysis
What is cyrolite?
Cyrolite is an aluminium compound that can reduce an ionic compounds melting points
What is Bauxite?
Bauxite is the ore that aluminium is found in
What is oxidation?
Oxidation is where an element loses electrons and the gain of oxygen
What is reduction?
reduction is where an element gains electrons but loses oxygen
What is electrolysis used for?
Electrolysis is used to separate metals from gases in ionic compounds
