The Ostwald process for the commercial production of nitric acid involves the following three steps:

4NH 3 ( g ) + 5O 2 ( g ) 4NO ( g ) + 6H 2 O ( g )

2NO ( g ) + O 2 ( g ) 2NO 2 ( g )

3NO 2 ( g ) +  H 2 O ( l ) 2HNO 3 , ( a q ) +  NO ( g )

a. Which reactions in the Ostwald process are oxidation–reduction reactions?

b. Identify each oxidizing agent and reducing agent.

(a)

Interpretation Introduction

Interpretation:

The steps involved in the Ostwald process are given and the oxidation and reduction reaction along with oxidizing and reducing agent is to be stated.

Concept introduction:

The gain of electrons and decrease in oxidation number is called reduction reaction whereas the loss of electrons and increase in oxidation number is called oxidation reaction.

When in a reaction both oxidation and reduction reaction occur simultaneously, it is known as a redox reaction.

To determine: The oxidation-reduction reactions in the Ostwald’s process.

Explanation of Solution

The equations corresponding to an oxidation-reduction reaction are as follows,

4NH3(g)+5O2(g)4NO(g)+6H2O(g)

3NO2(g)+H2O(l)2HNO3(aq)+NO(g)

The given chemical equations are,

4NH3(g)+5O2(g)4NO(g)+6H2O(g) (1)

2NO(g<
