redox reaction:
Redox reactions are oxidation-reduction chemical reactions in which the reactants undergo a change in their oxidation states. The term ‘redox’ is a short form of reduction-oxidation. All the redox reactions can be broken down into two different processes – a reduction process and an oxidation process.The oxidation and reduction reactions always occur simultaneously in the redox reaction or Oxidation-Reduction reaction. The substance getting reduced in a chemical reaction is known as the oxidizing agent, while a substance that is getting oxidized is known as the reducing agent.
The different types of redox reactions are:
type:
Decomposition Reaction
Combination Reaction
Displacement Reaction
example: A few examples of redox reactions, along with their oxidation and reduction half-reactions are provided in this subsection.
A reaction in which elements undergo both oxidation and reduction is termed as redox reaction.
Reduction and Oxidation can be differentiated on the basis of change in oxidation number.In reduction the oxidation number gets reduced and In oxidation there is gain in oxidation number.
Three types of redox reactions are as follows:
Decomposition reactions: When a compound is broken down into its constituent parts.
eg:CaCO₃ → CaO + CO₂
Displacement reactions: When one or more atoms are exchanged for another.
eg:Fe + CuSO₄ FeSO₄ + Cu
Disproportionation reactions:When a molecule is both reduced and oxidized simultaneously
eg: 2CuCl → Cu+CuCl₂
