Highly Versatile Industrial Acid

Nitric Acid is valued across various sectors, including agriculture, explosives manufacturing, metallurgy, and research laboratories. Its strong oxidizing nature makes it essential in producing fertilizers such as ammonium nitrate, as well as in etching and cleaning metals. The acid's wide applicability ensures continual demand in both large-scale and specialized industries.

Handling and Storage Safety

Due to its corrosive nature and vapor pressure of 7.7 kPa at 20C, Nitric Acid must be handled with extreme care. It is stored in HDPE drums, carboys, or tankers for added protection and stability. Tightly sealed containers shield the acid from light and heat, minimizing decomposition and ensuring a shelf life of up to 12 months. Always store it in well-ventilated, cool locations away from incompatible materials.

Quality, Compliance, and Supply

With a minimum purity of 68%, Nitric Acid is available under Technical and Analytical grades, meeting industry and laboratory requirements. As a regulated hazardous chemical (UN 2031, Hazard Class 8), its production, packaging, and transportation comply with national and international standards. Available across India, it is supplied by dealers, exporters, manufacturers, and traders for reliable sourcing.

FAQ's of Nitric Acid:

Q: How is Nitric Acid typically used in industrial applications?

A: Nitric Acid serves as a key raw material in the production of fertilizers, explosives, and for metal etching and cleaning processes. It is also widely utilized in laboratory analyses and chemical manufacturing due to its strong oxidizing properties.

Q: What are the recommended storage conditions for Nitric Acid?

A: Nitric Acid should be stored in tightly closed HDPE drums, carboys, or tankers in a cool, well-ventilated area. It must be kept away from heat, direct light, combustibles, and reducing agents to prevent decomposition and maintain its shelf life of 12 months.

Q: When does Nitric Acid decompose, and what are the byproducts?

A: Nitric Acid decomposes when exposed to light and heat, leading to the formation of nitrogen oxides (NOx) and oxygen as decomposition products. Proper storage prevents this process and ensures safety and effectiveness.

Q: Where can Nitric Acid be sourced in India?

A: Nitric Acid is widely available across India through reputable dealers, exporters, manufacturers, retailers, suppliers, and traders. It is provided in compliant packaging to ensure safe transport and handling.

Q: What safety precautions should be followed during Nitric Acid handling?

A: Protective equipment such as acid-resistant gloves, goggles, and aprons should always be used. Nitric Acid causes severe skin burns, eye damage, and can corrode metals. It should only be handled by trained personnel in well-ventilated environments.

Q: What are the main benefits of using Nitric Acid in manufacturing?

A: Nitric Acid's strong reactivity and oxidizing nature accelerate key chemical processes, increase yield in fertilizer and explosives production, and improve precision in metal etching and cleaning. Its effectiveness enhances productivity and product quality.
