In the redox reaction
MnO 2 + 4H Cl → MnCl 2 + 2H 2 O + Cl 2
- MnO 2 is reduced to MnCl2& HCl is oxidized to H 2 O
- MnO 2 is reduced to MnCl 2 & HCl is oxidized to Cl 2
- MnO 2 is oxidized to MnCl 2 & HCl is reduced to Cl 2
- MnO 2 is oxidized to MnCl 2 & HCl is reduced to H 2 O
A REDOX reaction is where oxidation and reduction occur simultaneously in a reaction.
A substance is oxidised when:
- It gains Oxygen
- It loses Hydrogen
- It loses electrons
A substance is reduced when:
- It loses Oxygen
- It gains Hydrogen
- It gains electrons
- Here, MnO2 loses its oxygen to form MnCl2.
- Hence it is getting reduced.
- HCl loses its H to form Cl2.
- It is getting oxidised.
Therefore, the correct answer is (b) MnO 2 is reduced to MnCl 2 & HCl is oxidised to Cl 2
