7.2 Electrolysis Electrolytic cells Electrolysis is the decomposition of a compound into its elements by an electric current. Uses of electrolysis: to extract useful metals from their ores to produce useful by-products such as chlorine gas to purify metals...
7.1 Oxidation and Reduction Redox reactions Oxidation is: gain of oxygen loss of hydrogen loss of electrons increase in oxidation number Reduction is: gain of hydrogen loss of oxygen gain of electrons decrease in oxidation number Oxidation and...
CHAPTER 7: Redox Reactions and Electrolysis Oxidation and Reduction Electrolysis Learning outcomes: calculate oxidation numbers of elements in compounds and ions describe and explain redox processes in terms of electron transfer and/or changes in oxidation number...
