In this lecture you will learn about Practical Batteries and Electrolysis. First you will look at Primary Batteries such as the Leclanche Dry Cell and the more common Alkaline Cell. Then, you will shift into the Overall Reaction of the Fuel Cell before looking at Secondary Batteries such as the Car Battery. With Electrolysis, you discover the inner workings of an Aluminum Plant and Chromium Plating. Next you look at common Sodium Chloride before finishing off with Faraday's Laws, Corrosion of Iron, and Protection of Iron Against Corrosion with Tin.
batteries: lead-acid, Nicad; lithium ion
breaking down compounds by electric current
of electrolysis: Na and Cl2 from fused NaCl; NaOH and Cl2
from salt solution; copper refining; metal plating
= 96,500 coulombs = 96,500 As
examples of quantitative use of Faradays Laws e.g. Al production
of iron is an electrolytic process: needs both H2O and O2
protect iron by coatings and sacrificial Zn electrodes
