Which substance is oxidized and which is reduced in the following reaction MnO2 4HCl → MnCl2 Cl2 2H2O?

Answer: In the reaction MnO2 + 4HCl -> MnCl2 + Cl2 + 2H2O , Cl (chlorine) is the substance which is oxidized from the HCl, and it is the reducing agent for the MnO2 as well. As Cl is the oxidized substance in HCl, thus it is the oxidizing agent in the reaction.

What type of reaction is this MnO2 4HCl ⎯ → MnCl2 2H2O Cl2?

redox reaction
Hint: The given reaction is an example of a redox reaction. In these types of chemical reactions, the oxidation state of atoms or molecules gets changed.

What is the reducing agent in MnO2 4HCl?

In the reaction MnO2 + 4HCl -> MnCl2 + Cl2 + 2H2O , Cl (chlorine) is the substance which is oxidized from the HCl, and it is the reducing agent for the MnO2 as well. As Cl is the oxidized substance in HCl, thus it is the oxidizing agent in the reaction.

What is oxidising agent in MnO2?

The electronic configuration of Mn is 1s22s2p63s2p6d54s2. Therefore, it can lose 7 electrons and oxidation state can vary in between 0 to 7. In MnO2​, oxidation state of Mn is +4, which lies between highest and lowest oxidation state, so it can act as an oxidizing agent as well as reducing agent.

Which of the following statements about the given reaction are correct MnO2 4HCl → MnCl2 2 H2O Cl2?

in the above chemical equation, MnO2 is getting reduced to MnCl2 as reduction is called as removal of oxygen. MnO2 is acting as Oxidizing agent for HCl to become H2O as oxidation is called as addition of oxygen. Hence the option c is correct.

What is the oxidation number of MnCl2?

+2
There are two chlorine atoms, and the total oxidation number will be −1⋅2=−2 . Therefore, manganese’s (Mn) oxidation state is 2 or +2 , as we say in chemistry.

Which of the following statements about the given reaction are correct MnO2 4hcl → MnCl2 2h2o Cl2?

Which reaction are oxidation reduction reactions?

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

Is MnO2 + 4hcl -> MnCl2 + Cl2 + 2H2O an oxidizing or reducing agent?

Thank you for getting in touch with us for the answer of your query. In the reaction MnO2 + 4HCl -> MnCl2 + Cl2 + 2H2O , Cl (chlorine) is the substance which is oxidized from the HCl, and it is the reducing agent for the MnO2 as well. As Cl is the oxidized substance in HCl, thus it is the oxidizing agent in the reaction.

What happens when HCL is oxidized to Cl2?

Here HCl is oxidized to Cl2 and Mno2 is reduced to MnCl2. b. The reaction in which oxygen is either gained or hydrogen is lost by a substance is called oxidation reaction.

What is the oxidation number of MN in MnO2 +4hcl?

MnO2 +4HCl———->MnCl2+2H2O+Cl2. Here MnO2 is reduced to MnCl2. ie., the oxidation no.of Mn is decreased from +4 to -2. HCl is oxidised to chlorine molecule. ie.,the OXIDATION-NUMBER of chlorine is increased from -1 to 0. So MnO2 is reduced to MnCl2. HCl is oxidised to chlorine.

What is the difference between oxidation and reduction of MnO2?

Since oxidation is loose of electrons.. HCl is getting oxidised here.. Because the oxidation state of Cl in HCl is -1 whereas in Cl2 it is 0.. Hence HCl is oxidised by loosing an electron . On the other hand reduction is the gain of electron.. Hence MnO2 is getting reduced here because The oxidation state of Mn has changed from +4 to +2
