What are the types of redox reaction
Answers
Displacement
Dcomposition
Combustion
1. Combination Reactions
These are reactions in which two species (atoms or molecule) combine to form a single species. A combination reactions may be denoted in the manner:
A + B – C
2. Decomposition Reactions
Decomposition reactions are just the reverse of combination reactions. A decomposition reaction involves the breakdown of a compound into two or more components at least one of which must be in the elemental state.
3. Combustion Reactions
Combustion reaction is special category of combination reaction in which one of the element is oxygen.
4. Displacement Reactions
In these reactions, an atom or ion in a compound is replaced by an atom or ion of some other element. In general, it is represented by the equation,
X + YZ à XZ + Y
5. Disproportionation Reactions
A reaction in which the same species is simultaneously oxidised as well as reduced is called a disproportionation reaction. For such redox reactions to occur, the reacting species must contain an element which has atleast three oxidation states. The element in the reacting species is present in the intermediate oxidation state while the higher and lower oxidations states are available for reduction and oxidation to occur.
