Question

Describe the commercial methods for manufacturing

{NH}_{3}

and

{HNO}_{3}

. How are the starting materials obtained? What are their main uses? How is

{HNO}_{3}

concentrated?

Accepted Answer

${NH}_{3}$ can be produced by Haber's process:

The Haber's process offers a good case study to demonstrate how industrial chemists implement their knowledge of the factors that impact chemical equilibrium to search for the best conditions required to generate a good yield of products at a decent rate.

In Haber's process, the atmospheric nitrogen $N_{2}$ is changed to ${NH}_{3}$ , by reacting it with hydrogen $H_{2}$ . Here, a metal catalyst is implemented and high temperatures and pressures are preserved.

The raw materials for the method are

Air that supplies the nitrogen.

Natural gas and water that supply the hydrogen and the energy required to heat the reactants.

Iron that is the catalyst and does not get used up.

$N_{2} + 3 H_{2} \overset{Fe}{\to} 2 {NH}_{3}$

Uses:

In making of plastics, textiles, pesticides etc.

${HNO}_{3}$ can be prepared by Ostwald's process:

$4 {NH}_{3} + 5 O_{2} \to 4 NO + 6 H_{2} O + heat 2 NO + O_{2} \to 2 {NO}_{2} 4 {NO}_{2} + 2 H_{2} O + O_{2} \to 4 {HNO}_{3}$

Uses:

For making explosive, in fertilizers, making dyes etc.

${HNO}_{3}$ is a strong oxidizing agent; hence, has concentrated nature.
