Correct option is D
The correct answer is (D) 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.
