Oxidation-Reduction (Redox) Reactions
Defining of oxidation as the addition of oxygen removal of hydrogen;
Process of electron loss
Process of increase of oxidation number of a substance
Define reduction as the reverse of any of the above processes.
Calculating oxidation numbers of elements using a set of arbitrary rules:
(a) oxidation number of free elements = 0
(b) oxidation number of oxygen in any compound is except in peroxides where it is – 1
(c) oxidation number of H is + 1, except in hydrides where it is – 1
(d) the oxidation number of a neutral molecule or compound is zero e.g. H2SO4 =0 etc.
Use oxidation numbers to name inorganic compounds, to include the number of oxygen atom and water
molecules (if hydrated) determine the oxidation states number of common elements in their compounds
Defining of oxidizing and reducing agents in terms of addition and removal of oxygen and hydrogen respectively loss and gain of electrons change in oxidation numbers/states
