Oxidation and reduction take place together at the same time in the same reaction; These are called redox reactions; There are three definitions of oxidation.It is a reaction in which: Oxygen is added to an element or a compound; An element, ion or compound loses electrons; The oxidation state of an element is increased; There are three definitions of reduction.It is a reaction in which: Thus, a redox reaction that moves electrons or electron density from a less to a more electronegative atom will be spontaneous and release energy. Oxidation and reduction occurs in same reaction, so it is a redox reaction. Excercise Book Notes Redox Redox(printed notes) Get me outta here! A redox couple is defined as havingtogether the oxidised and reduced forms of asubstance taking part in an oxidation orreduction half reaction. Classification of Redox Reactions. So we say that carbon is oxidised.As this oxygen comes from the other reactant copper(II) oxide, copper(II) oxide loses oxygen and is hence reduced.. Redox Reactions class 11 Notes Chemistry.
