Question

an inorganic substance liberates o2 when heated turns an acid solution of kI brown and reduce acidified kmno4 the subtance is .
1so2
2.h2o2
3.kno3
4.pd(no3)2​

Answer 1

Answer:

option B ; H2O2

Explanation:

These are the oxidising and reducing properties of H2O2

Answer 2

Answer:

The correct Option is 2) i, e H2O2

Explanation:

as per the given question the reaction of the compounds will be like

Reactions:

2H 2O2when heated gives 2H 2O+O 2

​

2KI+H2O2 -------->Acidic Gives KOH+

Gives golden yellow colour to flame

​

Acidified KMnO 4

​acts as an oxidising agent when it is decolourised,

H2O2+O→H2O+O2

​

H2O2 Acts both as a reducing agent as well as an Oxidizing agent.

when H2O2 Is treated it releases O2 gas.

H2O2 turns acidic as we see in reaction of KI brown due to the formation of I2.
