Concept Introduction:
A balanced chemical equation is an equation that contains same number of atoms as well as of each element of reactants and products of reaction.
For example, the reaction between lead sulphide and oxygen is as follows:
Oxidation-reduction reaction is known as redox reaction. In these types of reaction one reactant is oxidized and another is reduced.
Oxidation: Oxidation is a process in which either 1 or all following changes occurs:
- Gaining of oxygen atoms.
- Loss of electrons.
- Loss of hydrogen atom.
Reduction: Reduction is a process in which either 1 or all following changes occurs:
- Loss of oxygen atoms.
