Question

Assertion:The reaction
MnO2 + 4HCl= MnCl2 + 2 H2O + Cl2
Is an example of redox reaction

Reason: I this reaction HCl is reduced to Cl2 whereas MnO2 is oxidized to MnCl2

Answer 1

Answer:

Assertion is true but reason is false.

Hcl is oxidised to cl2

Mno2 is reduced to Mncl2.

Hope it helps....

Answer 2

The assertion is true but the reason is false.

• A redox reaction is one which involves both oxidation and reduction reaction simultaneously.
• The electrons lost in the process of oxidation of one half of the reaction is taken up by the reactant which gets reduced. Hence the number of electrons lost and gained in a balanced redox reaction are equal.
• In this given reaction the Cl(-) in HCl is oxidized to Cl2 while the Mn(+4) in MnO2 is reduced to Mn(2+) in MnCl2.
