Question

MnO2 + 4HCl --> MnCl2 + 2H2O + Cl2

Identify :-

(i) Reduction
(ii) Oxidation.
(iii) Reducing agent
(iv) Oxidising agent.

And explain why.

Thanks

Answer 1

1] MnO2 has undergone reduction because its oxidation state has reduced from +4 to +2.
2] HCl has undergone oxidation to form Cl2 because its oxidation state has incresed from -4 to +0.
3] Cl2 is the reducing agent as it has undergone oxidation.
4]MnO2 is the oxidizing agent as it has undergone reduction.

Answer 2

Hi there!

MnO₂ + 4HCl → MnCl₂ + 2H₂O + Cl₂

Here,

1. REDUCTION :-
HCl has undergone reduction because its oxidation state has reduced.

2. OXIDATION :-
HCl has undergone oxidation to form Cl₂ because its oxidation state has incresed from -4 to +0.

3. REDUCING AGENT :-
Cl₂ is the reducing agent as it has undergone oxidation.

4. OXIDISING AGENT :-
MnO₂ has undergone reduction because its oxidation state has reduced from +4 to +2.

Hope it helps! :)
