FAQs on Applications of Nitric Acid

Is Nitric acid hazardous?

Nitric acid is a highly corrosive and hazardous chemical. It has a potential of inflicting very profound pain and because serious burn, cellular disarray, as well as impairment of respiratory tract and even eyes tissue. Should be taken properly, the safety measures, such as putting on the determination clothing and eyewear should be considered when handling nitric acid.

What are environmental impacts of nitric production?

Nitric acid production could be a source of environmental effect in which the emission of nitrogen oxides (NOx) into the atmosphere is the primary contribution. NOx can be a major pollutant and cause both air pollution and acid rain, and therefore it can influence landscapes and deteriorate human health.

How to store nitric acid?

Nitric acid should be kept in a cold, dry, well-ventilated spot, other than sources of heat and flammable materials. A glass or a plastic container with a tight screw cap, because it will be corrosive with the metals and organic matter, is advisable.

What is the role of nitric acid in food industry?

Nitric acid is not a food additive by itself. Nevertheless, it is applied in food production process for equipment sanitation and disinfection elements to make sure that the food quality and safety are meet the required level. To avoid any residual nitric acid from contaminating any equipment used in food production, rinse it off properly.
