Question

For the reaction shown, identify the element oxidized, the element reduced, the oxidizing agent, and the reducing agent. KNO3 → KNO2 O2 Which element is oxidized? Which element is reduced? What is the oxidizing agent? What is the reducing agent?.

Answer 1

The oxidizing element is N and reducing element is O.

is act as an oxidizing agent as well as reducing agent.

Step-by-step explanation:

An Oxidizing agent is the agent which has ability to oxidize other or a higher in oxidation number.

Reducing agent is the agent which has ability to reduce other or lower in oxidation number. The given reaction is :

act as an oxidizing agent.

The oxidation number of N in is calculated as:

(+1)+(x)+3(-2) = 0

x = +5

And the oxidation number of N in is calculated as:

(+1)+(x)+2(-2) = 0

x = +3

From the oxidation number method, we conclude that the oxidation number reduced this means itself get reduced to and it can act as an oxidizing agent.

act as a reducing agent.

The oxidation number of O in is calculated as:

(+1)+(+5)+3(x) = 0

x = -2

The oxidation number of O in is Zero (o).

Now, we conclude that the oxidation number increases this means itself get oxidized to and it can act as reducing agent.

Answer 2

Oxygen is oxidized Nitrogen is the oxidizing agent

Nitrogen is reduced Oxygen is the reducing agent
