MnO + 4HCl -- MnCl2l_2l2​ + 2H2OH_2OH2​O + Cl2l_2l2​​​→​​​​ ​→​​​​ ​→​​​​ According to the given reaction, which of the following statements
Question

MnO + 4HCl -- MnCl2l_2 + 2H2OH_2O + Cl2l_2

According to the given reaction, which of the following statements is INCORRECT?


A.

MnO2O_2 is reduced to MnCl2MnCl_2​​

B.

It is a redox reaction.

C.

HCl is oxidised to Cl2l_2​​

D.

Cl2l_2 is oxidised to HCl​

Correct option is D

The correct answer is (D)  Cl2Cl_2 is oxidised to HCl.

The statement "Cl₂ is oxidised to HCl" is incorrect.

Information booster:

  • In this reaction, MnO₂ is reduced to MnCl₂, and HCl is oxidized to produce Cl₂.
  • Reduction involves the removal of oxygen or the gain of electrons.
  • Oxidation involves the addition of oxygen or the loss of electrons.
  • Here, MnO₂ acts as an oxidizing agent, while HCl acts as a reducing agent.
  • This process is a redox reaction, meaning both oxidation and reduction happen simultaneously.

This reaction demonstrates how manganese dioxide facilitates the release of chlorine gas through a redox process.
