Question

2.2 Identify the correct statement from the foowing:
a) MnO2 is getting reduced whereas HCl is getting oxidized.
b) MnO2 is getting oxidized whereas HCl is getting reduced .
c) MnO2 and HCl both are getting reduced. d) Mnoz and HCl both are getting oxidized.​

Answer 1

Answer:

option a) is correct

Explanation:

MnO₂ is has to lose oxygen . ∴ is being reduced

HCl has to lose hydrogen ∴ it is being oxidised

Concept :

Oxidation : addition of oxygen/removal of hydrogen

reduction : addition of hydrogen /removal of oxygen

Answer 2

The correct statement is a. $MnO_2$ is getting reduced whereas HCl is getting oxidized.

• $MnO_2+4HCl\rightarrow MnCl_2+2H_2O+Cl_2$
• The process in which oxygen is added to a substance is called oxidation. Whereas the process in which oxygen is removed from a substance is called reduction.
• In this reaction $MnO_2$ releases oxygen and get reduced to $MnCl_2$ .
• $HCl$ accepts oxygen atom and oxidised to $H_2O$.
