    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.
