Electrochemistry
Learning outcomes - after studying this topic, you should be able to:
- 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
