Electrolysis has important applications in everyday life - from the batteries in our portable devices to the production of common metals such as aluminum. Featuring lab demonstrations, engaging graphics and clear explanations, this program looks at the chemistry of electrolysis. Two types of electrochemical cells are introduced - galvanic cells and electrolytic cells - and compared. The program discusses the industrial applications of electrochemistry, including brine electrolysis, aluminum production, electroplating and anodizing. Viewers are also introduced to the many applications of rechargeable batteries, such as lead-acid, Ni-MH and Li-ion batteries before concluding with an introduction to Faraday's First Law of Electrolysis and stoichiometric calculations.
