Key knowledge:
• electrolysis of molten liquids and aqueous solutions using different electrodes
• the general operating principles of commercial electrolytic cells, including basic structural features and selection of suitable electrolyte (molten or aqueous) and electrode (inert or reactive) materials to obtain desired products (no specific cell is required)
• the use of the electrochemical series to explain or predict the products of an electrolysis, including identification of species that are preferentially discharged, balanced half-equations, a balanced ionic equation for the overall cell reaction, and states
• the comparison of an electrolytic cell with a galvanic cell with reference to the energy transformations involved and basic structural features and processes
• the application of stoichiometry and Faraday’s Laws to determine amounts of product, current or time for a particular electrolytic process.
