• reducing agents are electron donors
• oxidising agents are electron acceptors
• in redox reactions, the reducing agent is oxidised (loses electrons) and becomes more positive
• the oxidising agent is reduced (gains electrons) and becomes negative
• A redox reaction involves two processes, reduction and oxidation
• The oxidation state is the apparent charge of an atom in a free element, a molecule, or an ion
• Oxidation describes a process in which the oxidation state increases and reduction describes a process in which the oxidation state decreases
