explain any three type of redox reaction and give suitable example
Answers
Answer:
Redox reactions are matched sets: if one species is oxidized in a reaction, another must be reduced. Keep this in mind as we look at the five main types of redox reactions: combination, decomposition, displacement, combustion, and disproportion
The formation of hydrogen fluoride is an example of a redox reaction. We can break the reaction down to analyze the oxidation and reduction of reactants.
hope it helped you dear friend
What are Redox Reactions?
A redox reaction can be defined as a chemical reaction in which electrons are transferred between two reactants participating in it. This transfer of electrons can be identified by observing the changes in the oxidation states of the reacting species.
An illustration detailing the electron transfer between two reactants in a redox reaction is provided below.
In the illustration provided below, it can be observed that the reactant, an electron, was removed from reactant A and this reactant is oxidized. Similarly, reactant B was handed an electron and was therefore reduced.
The loss of electrons and the corresponding increase in the oxidation state of a given reactant is called oxidation. The gain of electrons and the corresponding decrease in the oxidation state of a reactant is called reduction.
Electron-accepting species which tend to undergo a reduction in redox reactions are called oxidizing agents. An electron-donating species which tends to hand over electrons can be referred to as a reducing agent. These species tend to undergo oxidation. It can be noted that any redox reaction can be broken down into two half-reactions, namely the oxidation half-reaction and the reduction half-reaction.
When writing these half-reactions separately, each of them must be balanced in a way that all the electrons are accounted for.
Types of Redox Reactions
The different types of redox reactions are:
Decomposition Reaction
Combination Reaction
Displacement Reaction
Disproportionation Reactions
Decomposition Reaction
This kind of reaction involves the breakdown of a compound into different compounds. Examples of these types of reactions are:
2NaH → 2Na + H2
2H2O → 2H2 + O2
Na2CO3 → Na2O + CO2
All the above reactions result in the breakdown of smaller chemical compounds in the form of AB → A + B
But, there is a special case that confirms that all the decomposition reactions are not redox reactions.
For example CaCO3 → CaO + CO2
