Reaction of MnO2 with aqueous HCI

Identify the correct statement from the following:a)MnO2 is getting r...
The correct statement is option 'A': MnO2 is getting reduced whereas HCl is getting oxidized.
Explanation:
In a chemical reaction, oxidation refers to the loss of electrons by a molecule, atom, or ion, while reduction refers to the gain of electrons. To determine whether a substance is getting oxidized or reduced, we need to look at the changes in the oxidation states of the elements involved in the reaction.
In the given options, option 'A' states that MnO2 is getting reduced and HCl is getting oxidized. Let's analyze this reaction in detail:
MnO2 + 4HCl → MnCl2 + 2H2O + Cl2
Here, MnO2 is the reactant and HCl is the reactant. MnO2 has a higher oxidation state for Mn (+4) compared to MnCl2 (+2). This means that Mn in MnO2 is getting reduced, as its oxidation state decreases from +4 to +2. This reduction occurs by gaining 2 electrons.
On the other hand, HCl has a higher oxidation state for Cl (-1) compared to Cl2 (0). This means that Cl in HCl is getting oxidized, as its oxidation state increases from -1 to 0. This oxidation occurs by losing 1 electron.
Therefore, option 'A' is correct: MnO2 is getting reduced whereas HCl is getting oxidized.
In summary:
- MnO2 is getting reduced, as Mn's oxidation state decreases from +4 to +2.
- HCl is getting oxidized, as Cl's oxidation state increases from -1 to 0.
It is important to note that oxidation and reduction always occur together in a redox reaction. The substance that gets oxidized is called the reducing agent, and the substance that gets reduced is called the oxidizing agent. In this case, MnO2 acts as the oxidizing agent, and HCl acts as the reducing agent.
