3. Oxidation and Reduction
Oxidation and Reduction can be defined in two ways:
a) Loss or gain of oxygen and
hydrogen
b) Loss or gain of electron
4. Oxidation and Reduction in terms of Loss
and Gain of Oxygen and Hydrogen
Oxidation:
Gain of oxygen or loss of
hydrogen is called oxidation
Reduction:
Gain of hydrogen or loss of
oxygen is called reduction
7. Oxidation and Reduction in terms of
Loss and Gain of Electrons
Oxidation
• A process that involves the
loss of electrons is called
oxidation
Reduction
• A process that involves the
gain of electrons is called
reduction.
