Each group will present one project to the class, using powerpoint slides and oral presentation. Whenever applicable, use redox reactions, potentials, diagrams and pictures to convey your ideas. Your grades will depend on how well you explain the project, how well the audience understand it, and how well you handle Q&A. Project 1 Describe and explain how batteries work; show half reactions and potentials; explain how rechargeable batteries work and the difference between rechargeable batteries and non-rechargeable batteries. Presentation should have at least the following four types of batteries: alkaline batteries, lead storage battery, nickel-cadmium battery, and lithium-ion battery. You are welcome to present more. Project 2 Describe and explain how fuel cells work. Include at least two fuel cells (e.g. hydrogen-oxygen fuel cell, methanol fuel cell, etc.). Show anode and cathode reactions and the potentials. Pay attention to their applications, limitations, and future development. Project 3 Describe how corrosions occur (you can use iron as an example). Use electrochemistry and redox reactions. Discuss different ways to prevent corrosion. Project 4 Describe electrolysis and explain the difference between electrolytic cells and galvanic cells, using the electrolysis of water as example. Also describe the following commercial electrolytic processes: production of aluminum, electrorefining of metals (copper), metal plating (silver), electrolysis of sodium cholide. Project 5 Describe how ion-selective electrodes work; explain in detail pH electrode.

ion-selective electrodes


Ion-selective electrodes are the membrane electrodes which can
produce electrical potential through the process of converting the
actions of the ions which are dissolved into an aqueous solution
(Mikhelson, 2013).



The potential produced can be measured by use of a voltmeter or pH
meter.
