Question

The reaction MN O2 + 4 HCL gives mncl2 + 2 H2O + cl2 is an example of redox reaction reason in this reaction HCL is reduced to cl2 whereas MN O2 is oxidised to mncl to

Answer 1

Answer:

O2

Explanation:

MnO2+4Hcl gives MnCl2+2H2O+Cl2

Reduced substance:MnO2

Oxdised Substance: Hcl

Oxidizing Agent : MnO2

Reducing agent : Hcl

Answer 2

Answer:

Both assertion and reason are true and reason is the correct explanation of the assertion.

Explanation:

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

The oxidation state of Cl in HCL is -1 and it changes to 0 in the product Cl2. Increase in oxidation number occurs, so Cl- is oxidized.

In MnO2, Mn is +4 state and this becomes +2 in product MnCl2. So decrease of oxidation number occurs, hence Mn is reduced.

Hence, MnO2 is the oxidizing agent and HCl is the reducing agent.
