Why hno3 is transported in aluminium container?

Question

Answer

Answer

Concentrated HNOcan be transported into aluminium containers because concentrated nitric acid reacts with aluminium to form a protective layer of an oxide

This protective layer of the oxide makes the aluminium unreactive and renders it be passive. This unreactive aluminium cannot react with HNO and therefore there are no further chemical reactions.

This makes it easy for aluminium to be stored and transported safely in aluminium containers.

Hope it's help.

Answer

Because concentrated nitric acid reacts with aluminum to form a protective layer of an oxide . the protective layer of the oxide makes the aluminum unreactive and renders it be passive ..

Aluminium Container for Transporting HNO3

Introduction
HNO3, also known as nitric acid, is a highly corrosive and reactive chemical compound. It is widely used in various industries, including fertilizers, explosives, dyes, and pharmaceuticals. When it comes to transporting HNO3, it is crucial to select a suitable container that can ensure safety and prevent any potential hazards. One of the preferred choices for transporting HNO3 is an aluminium container. This choice is based on several factors, which will be discussed in detail below.

Corrosion Resistance
- Aluminium is known for its excellent corrosion resistance properties. It forms a thin but durable oxide layer on its surface when exposed to air, which prevents further corrosion.
- Nitric acid is a highly corrosive substance that can react with many materials, including metals. However, aluminium exhibits exceptional resistance to nitric acid corrosion due to the protective oxide layer.

Lightweight and Durable
- Aluminium containers are lightweight, making them easier to handle and transport compared to other materials, such as steel or glass.
- Despite being lightweight, aluminium containers are incredibly durable and can withstand rough handling during transportation without compromising their integrity.

Cost-effective
- Aluminium is abundant and relatively inexpensive compared to other materials used for chemical containers, such as stainless steel.
- Using aluminium containers for transporting HNO3 helps reduce costs without sacrificing safety and reliability.

Non-reactive
- Aluminium is considered non-reactive with nitric acid under normal conditions. It does not undergo any significant chemical reactions that would compromise the integrity of the container or the quality of the transported substance.
- This non-reactivity ensures that HNO3 remains stable during transportation, minimizing the risk of leaks or hazardous reactions.

Visual Appeal
- Aluminium containers can be visually appealing, providing a clean and professional appearance during transportation, especially when compared to other options like plastic containers.
- This visual appeal can be important when transporting HNO3 for commercial or industrial purposes, as it reflects a commitment to quality and safety.

Conclusion
In conclusion, transporting HNO3 in an aluminium container is a suitable choice due to its corrosion resistance, lightweight yet durable nature, cost-effectiveness, non-reactivity with nitric acid, and visual appeal. These factors ensure the safety and integrity of HNO3 during transportation, minimizing the risks associated with its corrosive nature.
