Question

Nitric acid has a wide range of applications in various industries. For this activity you are required to make a power point presentation discussing the following points:

• Countries that lead the production of nitric acid.
• Compounds which are manufactured using nitric acid as a key ingredient.
• Its significance in the production of fertilisers and rocket fuels.

Answer 1

Slide 1: Title Slide

• Topic: Industrial Applications of Nitric Acid (HNO₃)

Slide 2: Global Production Leaders

• Top Producing Countries: China, United States, Russia, and Germany lead global manufacturing.
• Production Method: Mostly produced on a massive industrial scale using the Ostwald Process (catalytic oxidation of ammonia).

Slide 3: Compounds Manufactured Using Nitric Acid

Nitric acid serves as a fundamental building block for key chemical compounds:

• Ammonium Nitrate: (NH₄NO₃), Used extensively globally.
• Explosives: TNT (Trinitrotoluene), Nitroglycerin, and Nitrocellulose.
• Nitrobenzene: Used to make dyes, aniline, and various pharmaceuticals.

Slide 4: Significance in Fertilisers

• Primary Source of Nitrogen: Plants require nitrates to synthesize proteins, but cannot absorb atmospheric nitrogen directly.
• Key Fertilisers: Nitric acid neutralizes bases to produce popular salts like Ammonium Nitrate and Calcium Nitrate.
• Impact: Essential for enriching soil nutrients and boosting global agricultural yields.

Slide 5: Significance in Rocket Fuels

• Powerful Oxidizer: Concentrated nitric acid (especially Red Fuming Nitric Acid or RFNA) provides dense oxygen molecules required for combustion.
• Space Application: Used in liquid-propellant rocket engines. It reacts spontaneously upon contact with specific fuels (hypergolic fuel systems), eliminating the need for an external ignition system in space.
