CaCO3 ➡Cao + CO2 is it redox reaction

Question

CaCO3 ➡Cao + CO2 is it redox  reaction

Answer

It is not redox reaction but it is decomposition

Answer

Redox Reaction of CaCO3 to CaO and CO2

CaCO3 is a chemical compound that consists of calcium, carbon, and oxygen. It is commonly found in rocks and minerals such as limestone and marble. When heated, CaCO3 decomposes to form CaO and CO2. This decomposition is a redox reaction because it involves the transfer of electrons between the reactants and products.

What is a Redox Reaction?

A redox reaction is a chemical reaction in which one or more elements undergo a change in their oxidation state. Oxidation is the process of losing electrons, while reduction is the process of gaining electrons. Redox reactions always occur in pairs because the electron that is lost by one element is gained by another element.

How does CaCO3 Decompose?

When CaCO3 is heated, it decomposes into CaO and CO2. The reaction can be represented as:

CaCO3 ➡ CaO + CO2

The oxidation state of carbon in CaCO3 is +4, while the oxidation state of carbon in CO2 is +4. Therefore, there is no change in the oxidation state of carbon during the reaction.

The oxidation state of calcium in CaCO3 is +2, while the oxidation state of calcium in CaO is +2. Therefore, there is no change in the oxidation state of calcium during the reaction.

The oxidation state of oxygen in CaCO3 is -2, while the oxidation state of oxygen in CO2 is -2. Therefore, there is no change in the oxidation state of oxygen during the reaction.

Conclusion

The decomposition of CaCO3 to CaO and CO2 is not a redox reaction because there is no change in the oxidation state of any of the elements involved in the reaction.

Answer

No. Because oxidation states of all the components are same in reactant's as well as product's side

Answer

reduction

Answer

It is not redox reaction , in order to say a reaction is redox reaction there must be change in the oxidation number of the interacting species
here CA has +2 oxidation no. in both the lhs and the
llly there is no change oxidation no. of c which is +4
and there is also no change in the o.s of oxygen which is -2
but since the compound is broken down into two different components it is known as decomposition reaction
