Oxidation
The loss of electrons by an element in its free state or an element in a compound
Reduction
The gain of electrons by an element in a compound
A reduction reaction
The removal of oxygen from a metal oxide to form pure metal
Everyday activities for oxidation and reduction
Action of bleaches
Rusting
Browning of cut fruits and vegetables
Food preservation
The breathalyzer test
Redox reactions
A chemical rection in which one ŕeactant is reduced and the other is oxidised
Oxidation half equation
The equation that only shows the loss of electrons
Reduction half equation
The equation that only shows the gain of electrons
Ionic bonding
Involves a transfer of electrons from the metal atom to the non-metal atom
Oxidation number
Indicates the number of electrons lost, gained or shared as a result of chemical bonding
Sum of oxidation numbers
All elements present in a polyatomic ion is equal to the charge on the ion.
In redox reactions
Oxidation number of one element will increase and the oxidation number of another will decrease
Oxidizing agent
brings about the oxidation of the other reactant
Reducing agent
Brings about the reduction of the other reactant
