Identify oxidation and reduction half-reactions, and combine them into a balanced redox reaction
explain how a Galvanic cell is constructed to draw a current from a redox reaction
use the activity series to decide which element or compound is the stronger oxidant
calculate the (standard) cell potential and determine the spontaneous direction of a redox reaction under standard conditions
calculate the cell potential for standard and non-standard conditions from the half-cell reactions, and determine the spontaneous direction of a redox reaction
calculate equilibrium constants from standard cell potentials and vice versa
combine reaction quotient and cell potential information to solve for unknown concentrations both at equilibrium and away from equilibrium
identify the key design features of an electrochemical sensor, and calculate an unknown concentration for appropriate electrochemical data
define electrolysis, electrorefining and overpotential
calculate the yield of a chemical product from current and electrolysis time
predict which products are thermodynamically favoured to form in an aqueous electrolysis reaction, and relate this to the chlor-alkali process
