3. Electrolytic Cells Shipwrecks and Salvage >Electrolytic cells involve oxidation-reduction reactionsStudents learn to:describe, using half-equations, what happens at the anode and cathode during electrolysis of selected aqueous solutionsdescribe factors that affect an electrolysis reaction – effect of concentration – nature of electrolyte – nature of electrodesStudents:plan and perform a first-hand investigation and gather first-hand data to identify the factors that affect the rate of an electrolysis reactionExtract from Chemistry Stage 6 Syllabus (Amended October 2002). © 2009, Board of Studies NSW.
