Use the electrochemical series to identify the strongest oxidant and reductant in an electrolytic cell containing an aqueous electrolyte solution. Predict the physical reactions and half-equations at the anode and cathode for different cells. Observe the reactions to confirm your predictions. Deduce the equation for a net cell reaction, where one can be written. This learning object is one of a series of four learning objects.
Objective
1. Students identify the species in electrolytic cells and the relevant half-equations in the electrochemical series.
2. Students identify all the oxidants and reductants present in a cell, which includes considering the electrode material.
3. Students deduce the species to be preferentially discharged at specific electrodes.
4. Students predict the half-equations for reactions at electrodes, and the expected observations.
5. Students identify whether an equation for the net cell reaction can be written and if so, what that equation will be.
