REDOX REACTIONS
A reaction during which electron transfer takes place
Electron Transfer
During ionic bonding between a metal & non-metal, electron
transfer occurs redox reaction
A redox reaction consists of 2 half-reactions that occur
simultaneously and combine to produce the net reaction
Oxidation
A loss of electrons
Reduction
A gain of electrons
Oxidising Agent
A substance that is reduced / gains electrons
Causes the oxidation of the other substance
Reducing Agent
A substance that is oxidized / loses electrons
Causes the reduction of the other substance
Types of Reactions
During ionic bonding, the metal ion acts as the reducing agent (is
oxidized) & the non-metal acts as the oxidising agent (is reduced)
In the 'magnesium burns in oxygen' reacting, Mg is oxidized
reducing agent & O2 is reduced oxidising agent
